1999 apr 14 10 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H 6.1 record-mute mode or head identi?cation selection pin rmhid allows input of two independent digital control signals for selecting the record-mute or head identification modes which are voltage coded. the rm control signal is selected via a 10 k w resistor and the hid control signal is selected via a 18 k w resistor. this set-up enables the two signals within the TDA9605H to be separated. the rm control signal is only in use during the record mode (bit afm = 1); during the playback mode (bit afm = 0) the rm signal is ignored. pin rmhid should be connected to ground when the rm control signal is not used. the use of the rm control signal is optional since the same function is available via the i 2 c-bus control in the record-mute mode. however, accurate timing of recording start and stop may sometimes be difficult to realize via the i 2 c-bus control. in this event the rm control signal can be used instead. there is also the possibility to use the record-mute mode control line of the video head amplifier. 6.2 hi-? audio output level when the application circuit is used in accordance with the application diagram, the standard fm deviation of 50 khz equals a 1 khz audio signal of - 8 dbv line output level (bit loh = 0). a different standard audio level can be selected by changing the external filter components of the noise reduction on pins emphl and emphr (see section 14.3). the standard audio level changes proportionally to the impedance of the external de-emphasis filter. 6.3 reference current the external resistor connected to pin i ref defines the internal reference currents and determines the temperature stability of circuits adjusted by the auto-calibration function. 6.4 head ampli?er 6.4.1 p layback mode the playback mode is selected by setting bit afm = 0. during the playback mode the input circuit on pins pbin2 and pbin1 is enabled (see fig.6). pin recout is disabled and pin hmsw shows a low impedance to ground, so realizing an ac ground for the head circuit via the external capacitor connected between these pins. the head identification (hid) signal on pin rmhid selects between the head signals on pins pbin2 or pbin1. head selection is defined as shown in table 1. the state of the rm control signal on pin rmhid is dont care in the playback mode. i 2 c-bus control bits hac2, hac1 and hac0 offer a wide selection of playback amplification to fit different head and head transformer specifications. the advised setting of the playback amplification realizes a level of 24 mv (rms) for each carrier signal after the head amplifier to obtain a 17 db overhead compared to the auto-normal level (hi-fi detection). however, performance is not critical and a different setting can be used if desired. the carrier level can be measured using the hf envelope output voltage on pin envout (bit eos = 1). during standard operating mode the hf envelope signal is derived from the left channel carrier amplitude (1.3 or 1.4 mhz carrier) but the special test 10 of the test mode also enables the hf envelope output of the right channel carrier amplitude (1.7 or 1.8 mhz carrier). the advised carrier playback level of 24 mv (rms) equals an hf envelope voltage of 3.3 v. the head amplifier output signal can be monitored directly by using test 8 of the test mode. pin envout functions as the test output showing 6 db attenuation compared to the actual head amplifier output level (see section 14.4). table 1 selection of the head signal 6.4.2 r ecord - mute mode the record-mute mode is selected by setting bit afm = 1 and either setting bits doc, shh and deth to logic 0 or switching the rm control signal to high-level. during the record-mute mode no recording current is present on pin recout (see fig.6). the head amplifier status actually equals the playback mode, however, the second amplifier stage is disabled to minimize power consumption. the rm control signal on pin rmhid enables fast switching between the record and record-mute modes (see table 2). if the i 2 c-bus control is set to the record mode, the use of record-mute mode control via pin rm allows for accurate timing of recording start and stop, independent of the i 2 c-bus control (see section 6.1). hid signal level on pin rmhid selection of head signal low lower than 0.6 v or between 2.65 and 3.8 v pin pbin2 (head 2) high between 1.0 and 2.35 v or higher than 4.3 v pin pbin1 (head 1)
1999 apr 14 11 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H table 2 selection of recording modes 6.4.3 r ecord mode the record mode is selected by setting bit afm = 1 and setting bits doc, shh and deth from logic 001 to 111 and switching the rm control signal to low-level. during the record mode actual recording is activated and the recording current is output on pin recout (see fig.6). pins pbin2 and pbin1 form a connection to the 5 v head amplifier supply voltage (v cch ). pin hmsw is internally connected to pin recout and the external capacitor has no function in this mode. the desired carrier mix ratio is set via i 2 c-bus control bits doc, shh and deth. a wide selection of recording currents is available to fit different head and head transformer specifications and are set via bits hac2, hac1, hac0 and range bit hrl. the setting of the carrier mix ratio does not change the selected recording current. rm signal level on pin rmhid record mode low lower than 2.35 v record or record-mute mode as de?ned by i 2 c-bus control high higher than 2.65 v record-mute mode the dc bias current on pin recout is changed proportional to the selected recording current for optimizing the performance and minimizing the power consumption for each recording current selected. a boucherot damping circuit is connected between pin hmsw and ground to prevent head current resonance peaking. a capacitor of 10 nf and a resistor of 470 w are specified in fig.14, but the component values are not critical. 6.4.4 h ead amplifier power supply and ground the head amplifier is supplied via a separate 5 v supply (pin v cch ) and ground (pin gndh). a capacitor of 100 nf should be placed close to the device between pins v cch and gndh for proper decoupling of the power supply. the head amplifier ground (pin gndh) should be connected to the main ground (pin gnd). fig.6 simplified circuit diagrams of the head amplifier modes. handbook, full pagewidth mgr841 35 k w gndh gndh ah2 pbin2 pbin1 hmsw recout ah1 35 k w gndh TDA9605H 38 37 36 35 pbin2 pbin1 hmsw recout 38 37 36 35 5 w gndh ah2 ah1 v cch v cch TDA9605H a. playback mode and record-mute mode. b. record mode.
1999 apr 14 12 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H 6.5 automatic calibration the integrated auto-calibration system is activated by means of bit cals of the power byte (see fig.7). the auto-calibration system ensures hi-fi processing is well in accordance with the vhs hi-fi system standard by an automated adjustment of carrier frequencies, band-pass filters and noise reduction filters. calibration is only needed after start-up of the video recorder. the calibration settings remain stable as long as the supply voltage (v cc ) is present. auto-calibration is only executed in the record-mute mode or record mode and no standby mode or test mode should be selected, i.e. auto-calibration requires the setting of bit afm = 1, bit stbp = 0, bit stba = 0 and bit test = 0. auto-calibration is started after setting bit cals = 1. calibration is performed fully automatically, using the hid control signal as a time reference. audio signals are not disturbed during the calibration process. calibration of the oscillator frequencies is performed by measuring the number of oscillator cycles within one period when the hid control signal is at high-level and comparing this result with an internal value stored in the read only memory (rom). four different rom values are available for ntsc or pal (secam) system calibration of both the left and right channel carrier. in case of ntsc a special routine is active for the calibration of the right channel carrier which results in a frequency difference between the left and right channel carrier near to 401.2 khz. this value effectively reduces the crosstalk from hi-fi carriers to video colour signal as present during extended play (ep) tape speed. ntsc calibration uses a standard hid control signal of 29.97 hz (pulse width =16.683 ms) where pal calibration uses a standard hid control signal of 25 hz (pulse width = 20 ms). after auto-calibration the maximum frequency error is 5 khz assuming a time error of maximum of 5 m s when the hid control signal is at high-level. jitter on the hid control signal should not exceed 1 m s to realize ep optimization within 2 khz for ntsc. in general, the crystal based hid control signal available in the video recorder can be used without modification. when the calibration of the oscillators is completed the band-pass filters are calibrated. the integrated weighting and fm de-emphasis filters of the noise reduction are calibrated at the same time. the total auto-calibration time needed is maximum 17 cycles of the hid control signal. completion of the calibration is signalled by bit calr =1 of the read byte. the calibration can also be monitored by means of the envelope output. for this purpose the voltage on pin envout is forced to >2.5 v during the calibration. the audio signal to the audio envelope function (level meter) should be muted (i.e. output select = mute). fig.7 example of automatic calibration flow. handbook, full pagewidth mgr842 logic 1 logic 0 logic 1 logic 0 4 v 3 v 5 v calibration ready i 2 c-bus write bit cals i 2 c-bus read bit calr envout output rmhd input left channel oscillator right channel oscillator band-pass and noise reduction filters
1999 apr 14 13 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H otherwise, the audio envelope output voltage may become >2.5 v which makes it impossible to detect the completion of the calibration on pin envout. calibration relies upon the frequency accuracy of the hid control signal. the calibration result may be incorrect when the hid control signal is disturbed during a critical part of the calibration. an additional check is incorporated to detect such a situation by reading bit cale during calibration. when bit cale = 1, the calibration result is detected to be unreliable due to external causes. a new auto-calibration can be started by setting bit cals = 0 followed by setting bit cals = 1. bit cale always reads logic 1 when bit cals is logic 0. the oscillators and band-pass filters can be switched between ntsc and pal system frequencies after a calibration in ntsc or pal mode without the need of additional calibration. switching between these system modes is executed immediately and can be done in any operating mode. the frequency accuracy of system switching is 100 3 khz for both carriers. to obtain the best possible frequency accuracy in the record mode it is good practice to recalibrate after system switching. 6.6 power muting switching off and on of the power supply voltage or using the built-in passive standby mode results in rising and dropping of the output dc voltages and causes strong disturbances on the output pins. the TDA9605H includes three integrated mute switches to block such disturbances so avoiding the need for an external mute circuit. pop-free line and rf converter output signals are realized by connecting the integrated power mute switches behind the line and rfc output capacitors. power muting is active when bit mute = 1 (see fig.8). power muting is automatically activated when v cc is switched on, because this situation is the power-on reset default state. the integrated mute switches on pins mutec, mutel and muter are closed and form a low-impedance path to ground. furthermore, the pins rfcout, linel and liner are current limited to - 1 ma to avoid excessive supply currents and to achieve good noise attenuation without the need for a series resistor between the output and mute pins. pins decl and decr are also current limited for using the integrated power mute switches or for assisting external muting. fig.8 examples of power mute control and the auto-mute function. handbook, full pagewidth mgr843 v cc auto-mute (v cc < 7 v) bit mute (i 2 c-bus) ( 1 ) ( 1 ) bit stbp (i 2 c-bus) mutec mutel muter rfcout linel liner output signal with power mute t mute t mute t mute t mute t mute auto-mute active operation power off power off active operation power off (standby) active operation passive standby (1) power-on reset.
1999 apr 14 14 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H during power muting the internal output signal is also muted. after the output dc voltage has been established power muting can be de-activated by setting bit mute = 0. now the mute switches are opened resulting in a high-impedance path of 100 k w to ground. the output current limiting is not active. power muting is also used in combination with the integrated passive standby mode (bit stbp = 1). during this mode the output circuits are switched off and the line, decoder and rf converter output voltages decrease to 0 v using a discharge current of 1 ma. do not set power mute mode and change the passive standby mode at the same time. power mute mode should be activated first, followed by switching on or off of the passive standby mode to avoid possible output glitches. it should be noted that the time needed for stabilizing the output dc voltage is proportional to the output capacitor value. a safe mute time is 200 ms using a 10 m f capacitor (t mute =c 20000 s). power muting consumes approximately 4 ma additional supply current, so to obtain minimum power consumption the mute mode should be de-activated after use. very good performance is achieved for power-up, power-down and passive standby mode switching. an auto-mute function is included which activates power muting when the supply voltage drops below 7 v. the performance of this auto-mute function depends upon the power voltage drop rate. the voltage drop rate should not exceed 1 v during 10 ms. the best performance independent of voltage drop rate is realized by activating the passive standby mode before switching off the power supply voltage (by setting bit mute = 1 and bit stbp = 1). 6.7 envelope output pin envout is an analog output for stereo audio level (e.g. level meter display) and for playback fm carrier level (e.g. auto-tracking). the functional diagram is given in fig.9 and the timing diagram is shown in fig.10. only one adc input is needed on the microcontroller for reading all the required information. during the playback mode the selection between audio level and carrier level information is realized by setting i 2 c-bus control bit eos (see table 3). the af envelope output is defined by the signal selection made at the output select. during the record mode bit eos offers the selection between the audio level of the output select or the audio level of the fixed hi-fi stereo signal. this is a helpful setting when the microcontroller uses the audio level information to adjust the hi-fi recording level (volume control). the hf envelope output signal is continuous and is derived from the left channel carrier. the hf envelope output exhibits a logarithmic characteristic (see fig.11). in a standard application circuit only the left channel carrier level is required to support auto-tracking or manual tracking. however, test 10 of the special test mode allows for the right channel carrier level output instead for measurement purposes (see section 14.4). the af envelope output as a function of the output level is given in fig.12. the af envelope circuit uses time multiplexing for the left and right channel audio level. a peak-hold function and dynamic range compression (square root function) are included for easy read out. the peak-hold function and the left and right channel multiplexing are controlled by the hid control signal on pin rmhid (see table 4). table 3 selection of the envelope output table 4 af envelope output with channel multiplexing mode bit afm bit eos envelope output function playback 0 0 af envelope: via output select level meter display 1 hf envelope auto-tracking or manual tracking display record 1 0 af envelope: via output select level meter display 1 af envelope: hi-? stereo record volume control (and level display) hid signal level on pin rmhid af envelope output low lower than 0.6 v or between 2.65 and 3.8 v left channel audio peak level high between 1.0 and 2.35 v or higher than 4.3 v right channel audio peak level

1999 apr 14 17 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H 6.9 audio dubbing the TDA9605H includes unparalleled functionality supporting the audio dubbing function of hi-fi video recorders. audio dubbing is a feature which enables the recording of new sound material on the linear audio track (i.e. normal sound) of an existing recording. the dub-mix mode is selected by setting bit is2 = 1, bit is1 = 0 and bit is0 = 1. audio dubbing can be used in two different ways: output mix input mix. 6.9.1 o utput mix a new additional recording is made on the linear audio track. in the playback mode, the new linear audio sound and the original hi-fi sound are combined. in this way the hi-fi stereo quality remains and the linear audio sound is partly used (e.g. for commentary only). however, there is no control over the original hi-fi sound. mixing of the hi-fi and normal sound signals in the playback mode is supported by the output select function mix-left, mix-right and mix-stereo (bits osn, osr and osl) and creates a new fixed output signal of 1 2 hi-fi plus 1 2 normal. 6.9.2 i nput mix a new complete recording is made on the linear audio track (see fig.4). in the playback mode, only the linear audio sound is used. in this way the hi-fi stereo quality is lost, but total freedom in defining the new sound material is an extra advantage. furthermore, such recording is no longer restricted to playback on hi-fi video recorders (with an output mix option). the circuit changes into a mixing desk when using the dub-mix mode of the input select function in combination with the volume setting of normal select. a new linear audio recording can be created by mixing together the new and the original sound. continuous user control over amplitude and ratio mix of the auxiliary input signal (e.g. a microphone input) and the original hi-fi playback sound is possible using the left and right channel volume controls. this function is realized inside the ic by connecting the auxiliary input signal pair (pins auxl and auxr) to the left channel volume control and the hi-fi output signal pair to the right channel volume control. the settings of the output select function are used to arrange the hi-fi selection and the output signals in the dub-mix mode. however, some of these settings are overruled in the dub-mix mode. the normal signal is available on the line outputs for monitoring the dub-mix recording signals in the output select function modes mix-left, mix-right and mix-stereo. mix-stereo of the output select function is generally used for audio dubbing. in combination with the volume setting of normal select, user control over amplitude and ratio is offered for the auxiliary and the hi-fi signal as follows: ( 1 4 aux left + 1 4 aux right) volume left plus ( 1 4 hi-fi left + 1 4 hi-fi right) volume right. the dub-mix mode is to be used in the (hi-fi) playback mode. in the record mode, a signal loop from output to input can be closed which may cause audio oscillation. the auto-normal switching is not active during the dub-mix mode. the hi-fi sound is muted when no hi-fi input signal is detected; bit autn is not affected. table 5 dub-mix mode output select mode dub-mix output selection dub-mix input left channel right channel mute mute aux stereo mute hi-? left hi-? left aux stereo hi-? left hi-? right hi-? right aux stereo hi-? right hi-? stereo hi-? stereo aux stereo hi-? stereo normal normal aux stereo mute mix-left normal aux stereo hi-? left mix-right normal aux stereo hi-? right mix-stereo normal aux stereo hi-? stereo

TDA9605H 7.9.7 s tandby select the TDA9605H is switched in the low-power active standby mode by setting bit stba = 1. most circuits are switched inactive for reducing power consumption. however, the rf converter, line and decoder outputs remain active in this mode and the direct audio selections offered via the line select function and the decoder select function remain available. the selected output signal is muted during the active standby mode. the TDA9605H is switched in the minimum power passive standby mode by setting bit stbp = 1. all circuits are switched inactive to obtain minimum power consumption except for the power mute circuit, the i 2 c-bus and the line input reference buffer (i.e. the dc voltage on pins 1 to 11 remains active). when bit stbp = 1 a discharge current of 1 ma is active on pins rfcout, linel, liner, decl and decr. power muting ensures disturbance-free switching of the line and rf converter outputs to and from the passive standby mode. in the passive standby mode power muting can be de-activated again to achieve minimum power consumption. the calibration and i 2 c-bus registers are not affected in the active standby or passive standby mode. table 34 standby passive (bit stbp) and standby active (bit stba); note 1 notes 1. x = dont care. 2. power-on reset state. 7.10 read byte the read byte is used for reading the device state information. stbp stba mode description 0 0 operating standard operating mode: full function; note 2 0 1 active standby active standby mode: reduced power consumption 1 x passive standby passive standby mode: minimum power consumption 7.10.1 c alibration ready the completion of calibration is signalled by changing bit calr from logic 0 to logic 1. bit calr remains logic 0 if for some reason a calibration can not be completed (i.e. no hid control signal available or the hi-fi processing is in the playback mode). bit calr will also return to logic 0 if calibration is lost due to a power-on reset situation. additional information about the calibration result is available via bit cale. calibration is found correct if bit calr = 1 and bit cale = 0. pin envout can also be used to monitor calibration (see section 6.5). table 35 calibration ready (bit calr) note 1. power-on reset state. 7.10.2 a uto - normal selection the auto-normal function is activated when no hi-fi carrier input signal is detected in the playback mode. the auto-normal function overrules the settings of the output select function and selects normal sound (i.e. linear audio) instead of hi-fi. the state of the auto-normal function can be checked by reading bit autn. the auto-normal function and therefore bit autn is only valid in the playback mode. bit autn is always logic 0 in the record mode. table 36 auto-normal (bit autn) note 1. power-on reset state. calr description 0 not calibrated; note 1 1 auto-calibration completed autn description 0 hi-? carrier available; audio fm signal is detected from tape in playback mode; note 1 1 normal sound selected instead of hi-? carrier; no audio fm signal is detected from tape

1999 apr 14 49 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H 17 soldering 17.1 introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations reflow soldering is often used. 17.2 re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 230 c. 17.3 wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 17.4 manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
1999 apr 14 50 philips semiconductors product speci?cation audio processor with head ampli?er for vhs hi-? TDA9605H 17.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package soldering method wave reflow (1) bga, sqfp not suitable suitable hlqfp, hsqfp, hsop, htssop, sms not suitable (2) suitable plcc (3) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (3)(4) suitable ssop, tssop, vso not recommended (5) suitable
