1995 mar 21 9 philips semiconductors preliminary speci?cation audio processor for vhs hi-? and linear audio TDA9614H 6.1 audio i/o switching 6.1.1 i nput s elect (i nput s el ) for the audio fm circuitry eight different audio signals can be selected. the selection made here for hi-fi is also available for the linear audio circuitry. 1. tuner (stereo input; internal tuner of vcr). 2. cinch (stereo input; connection to hi-fi set). 3. ext1 (stereo input; tv scart1). 4. ext2 (stereo input; decoder, 2nd vcr scart2). 5. ext3 (stereo input; front cinch for e.g. camcorder). 6. sap (mono input; second audio program audio carrier for ntsc or conventional fm carrier with nicam reception). 7. normal (linear audio; [playback] signal of linear audio). when inserting a new video signal in an old audio/video recording the hi-fi audio track is erased. this setting can keep the current audio available on the hi-fi track by copying the (playback) linear audio signal to the hi-fi track during video insert. 8. ext3/st (input mix; mono ext3 on left, mono hi-fi on right channel). for linear audio use see section 6.1.2. 6.1.2 n ormal s elect (n orm s el ) for linear audio four settings can be selected: 1. inputsel (mono signal from input select). this is the standard setting. the signal source selected with the input select is led to the linear audio circuit. the linear audio agc should be switched on. 2. volume (mono signal from [hi-fi] volume control). the signal source selected with the input select has now volume control, the linear audio agc should be switched off. this setting is for use with audio dubbing: inserting a new audio signal on the linear track in an old audio/video recording. a special audio dubbing feature is now possible by selecting input mix ext3/st in the input select. this setting enables us to use the vcr as a mixer console: an audio source connected to ext3 (front cinch) can be adjusted and mixed together with the original hi-fi playback signal, using the left (ext3) and right (hi-fi playback) volume controls. 3. sap (sap input). this setting enables simultaneous recording of the ntsc sap signal on the linear track and tuner stereo on the audio fm track. when receiving a nicam audio signal, the linear audio can be used as a backup track when received television signals are weak. 4. tuner left (left channel [language 1] of tuner input). when receiving dual language transmissions the main language (language 1) can be recorded on linear audio. note that if the sap input is not used it can be connected to the right tuner channel, enabling language selection for linear audio. 6.1.3 v olume l/r; agc the volume controls are mainly intended for level adjusting of the audio signals to be recorded on the hi-fi track, however using the volume setting in the normal select it can also be used to control linear audio. the volume controls have a control range of +14 db to - 49 db in 1 db steps and a full mute. because the volume controls are i 2 c-bus controlled their actual behaviour is defined by the vcrs software. for instance user control can be volume only, left + right, volume + balance or the setting can be defined by a digital agc software loop using the signals at the dc (vu meter) outputs. the linear audio level can be controlled by an agc circuit, which can be switched off when desired. in most cases the agc should be used at all settings of the normal select except for volume. 6.1.4 a udio fm o utput m ute (afom ute ); n ormal o utput m ute (nom ute ) the audio output signal of the audio fm circuit can be muted with afomute, the linear output signal can be muted using nomute. if one of these signals is not used as an output (or input) signal it is best muted to further minimize crosstalk. 6.1.5 o utput s elect (o ut s el ) this block is the main output select function, possibly functional on all outputs. each output however has some means to override this selection for its own output signal, to implement extra features. eight selections are possible and they are shown in table 1.
1995 mar 21 10 philips semiconductors preliminary speci?cation audio processor for vhs hi-? and linear audio TDA9614H table 1 output select possibilities note 1. stereo is the standard setting, left and right are for language selection. using the tuner as input or output signal (record or loop-through of audio fm) the vcr can automatically switch from stereo to left (language 1) when a dual language transmission is received. if the vcr is in playback mode and no hi-fi track is present (checking bit afom via the i 2 c-bus or using the level at pin 11) the vcr can switch the output select to normal (or let the ic do this automatically by setting bit autn). if a hi-fi track is present the user may want to switch to left and right if the recording made was a dual language recording. furthermore the user may want to switch from a hi-fi selection to normal, e.g. when a complete audio remix has been created on the linear track using audio dubbing (see section 6.7). audio dubbing can also be used to re-record the linear track with e.g. only commentary. combined playback of this commentary together with the original hi-fi sound is then possible by means of a mix mode. 6.1.6 rf c onverter m ute (rfcm ute ) the rfc output is a mono output derived from the output select, its output signal can be muted. 6.1.7 l ine s elect (l ine s el ) the line output select is normally connected to both cinch (hi-fi set) and television (scart1). normally the audio signal from the output select will be available at this output, but three extra selections are possible and they are shown in table 2. table 2 extra line select possibilities notes 1. a signal from a source at ext2 (laser disc or second vcr) can be connected to a television set at line out. because this is a direct connection from the input to the line output buffers it is fully independent of any mode setting of the ic. connection of a pay-tv decoder box to ext2 and using this selection together with selecting ext1 in the decoder select enables combined use of the decoder box by both tv and vcr. in europe, use of the scart connector status line can automatize this switching. 2. direct audio connection from input ext3. if the line 2 outputs and ext3 inputs are not used for external connections a built-in karaoke unit or sound processor can be inserted between line 2 and ext3. selection remark description stereo (1) hi-? stereo audio fm output signal left and right channel left hi-? left audio fm output signal left channel (language 1) right hi-? right audio fm output signal right channel (language 2) normal linear audio linear audio nor + st linear and hi-? mix of audio fm stereo and linear audio nor + l linear and left mix of audio fm left channel and linear audio nor + r linear and right mix of audio fm right channel and linear audio mute mute selection description normal linear audio, useful for monitoring during audio dubbing ext2 (1) audio from input ext2 ext3 (2) audio from input ext3
1995 mar 21 11 philips semiconductors preliminary speci?cation audio processor for vhs hi-? and linear audio TDA9614H 6.1.8 d ecoder s elect (d ecode s el ) the line 2 output is normally connected to a decoder box or e.g. a second vcr (scart2). normally the audio signal from the output select will be available at this output, but three extra selections are shown in table 3. table 3 extra decoder select possibilities notes 1. enables the use of a decoder box (connected to line 2 [ext2]) by the vcr. 2. decoder box connection to television set (see section 6.1.7). 6.1.9 h eadphone s elect (hps el ) the headphone output will normally carry the output select signal, however three more selections are possible and shown in table 4. table 4 extra headphone select possibilities note 1. the selections left and right make it possible to select a different language for the headphone as for the line outputs. a possible implementation is to invert always a language selection made at the output select. 6.1.10 h eadphone volume the headphone volume control has a control range of +16 db to - 47 db in 1 db steps and a full mute. 6.1.11 dc s elect (dcs el ) the vu meter output is normally connected to the headphone select, but can also be switched to stereo (hi-fi stereo, before the output select). when using the vu meter output signal to implement a digital agc (read the level at the dc output, and adjust the volume l/r controls accordingly) it is necessary to have information of selection description tuner (1) audio from input tuner ext1 (2) audio from input ext1 ext3 audio from input ext3 selection description left (1) left hi-? channel right (1) right hi-? channel normal linear audio, useful for monitoring the recording by audio dubbing both hi-fi audio channels, independent from the setting of output or headphone select. for this mode the selection stereo can be made. 6.2 linear audio circuits 6.2.1 r ecord / loop - through the signal selected with the normal select can be level controlled in the agc block. if wanted this agc can be switched off using bit agcn. the audio signal is thereafter dc decoupled using a capacitor between pin 29 (linout) and pin 28 (linin). from here on the signal goes to the output select and (in the event of record mode) to the record equalizer. the record equalizer is a non-inverting amplifier with a gain of +12 db, consisting of an opamp with feedback resistors, and acts as a pre-correction filter for the tape and head characteristics. the inverting input of the opamp is connected to pin 31 (receq), its output to pin 33 (recout). the circuit externally connected between pin 31 and ground defines the transfer of the record equalizer with equation: where: z is the complex impedance of the external circuit. two equalizings can be used, switching additional circuitry to ground with pin 30 (eqsw) in long play or extended play (i 2 c-bus: lp = 1). instead of the hi-fi circuit, linear audio has two loop-through modes: loop-through playback loop-through record. the only difference between loop-through record and record is the recout output, which is muted. the linrec output (pin 32) is used to drive the external high-voltage switch and possibly the bias oscillator. the linrec voltage has a small internal delay to be non-overlapping with the internal switching to playback mode. this ensures that no bias voltage will appear at the pbin input while the ic is in playback mode. 6.2.2 p layback the signal coming from the head is amplified and can be level controlled in 16 steps of 1 db. this setting can be used to adjust for spread or nominal difference in head output level. afterwards, the signal is frequency corrected in the playback equalizer. this equalizer includes the two standard vhs equalizing settings of 3180 and 120 m s a 3.98 1200 z + ( ) z ----------------------------- - =
1995 mar 21 12 philips semiconductors preliminary speci?cation audio processor for vhs hi-? and linear audio TDA9614H (standard play: lp = 0) and 3180 and 170 m s (long play: lp = 1). the signal is dc decoupled and routed to the output select via pins 29 and 28. when switching to or from playback the signal should be muted shortly using the normal output mute (nom) to prevent audible clicks caused by offset differences of the playback amplifier and agc. 6.3 audio fm circuits 6.3.1 r ecord / loop - through after low-pass filtering and signal compression in the noise reduction (nr) the audio signal is available at afnl and afnr. through a dc-decoupling capacitor the compressed audio signal is fed to an audio clipper at afml and afmr. subsequently, the audio signal is fm-modulated on a rf-carrier using an integrated current-controlled oscillator (cco). each cco (l and r) requires an external resistor (rccol/r) for temperature stability. through automatic calibration both the oscillator centre frequency and fm-deviation are adjusted. after low-pass filtering and summation of the two rf-carriers, the fm signal is available at fmout during record. during loop-through the fmout pin is inactive. the raf pin reflects the status of the raf-bit when it is used as output pin. in this case it is meant to switch the head amplifier between record and playback position. it can also be used as an input pin to overrule the raf-bit thereby forcing the ic in record or playback/loop-through position. 6.3.2 p layback the two fm modulated rf carriers, presented at fmin, are fed to an agc circuit. the agc operates on the peak level of the added bpf output signals. as a result, the input signal of the bpfs is kept constant for fmin voltages >30 mv (rms value) both carriers added. in this way the dynamic range of the integrated bpfs is optimally used over a large input signal range. subsequently, the rf carriers are bandpass filtered using two integrated bpfs. these bandpass filters are automatically calibrated as described in section 6.3.3. an external resistor (rbpf) is required for temperature stability. the filtered input signals are fed to a limiter. the limiter output signal is demodulated by means of a pll demodulator. the lf audio signal is fed through a sample-and-hold circuit to suppress head-switching noise. the demodulated audio is available at afml and afmr. through a decoupling capacitor the audio signal is applied to an audio low-pass filter at afnl and afnr. the low-pass filtered audio signal is expanded in the noise reduction. if the left channel carrier at fmin falls below the mute level of 4.2 mv (rms value) the audio signal is muted in front of the low-pass filter. this is achieved by comparing the left channel level detector signal with an internal reference. the mute timing is fixed by a capacitor at the cmute pin. if the level at cmute rises above a certain threshold, the pbmute bit is set. this will mute the audio signal. if bit autn has been set, the output selection will automatically switch to normal mode. the left channel level detector output is also available at pin envout. an agc correction voltage is added at this pin, such that the envout voltage indicates the left channel fm-carrier level even within the agc-range. the envout voltage can be used for auto-tracking of the fm-audio heads. in the event of drop-outs in the incoming fm signal, the left channel level detector is also used to activate the sample-and-hold. this drop-out cancellation is only active if bit doc has been set. 6.3.3 a utomatic calibration by means of bit cals the two integrated oscillators and bandpass filters can be calibrated in loop-through (lt) or record (rec) mode. normally this will be done after start-up of the vcr. after setting of bit cals the calibration procedure is automatically executed as shown in fig.4. the calibration starts at the first negative edge of hid after cals has been set. during the low period of hid (20 ms for pal) the number of oscillator cycles is compared to a certain value stored in a read only memory (rom). therefore, the final oscillator frequency is proportional to the inverse of the hid low-time. this means that an error of 1 m s in the hid low-time will result in an additional frequency error of approximately 100 hz. the maximum number of required hid cycles for one complete oscillator calibration is six, which is equal to 240 ms. after both oscillators have been calibrated the bandpass filters are calibrated using the right channel oscillator as reference frequency generator (1.6 mhz for pal). this will take <10 ms. bit calr is set to 1 if the calibration has been executed successfully. calr is 0 if: a power-on reset (por) has occurred. the calibration is running. the initial oscillator and bandpass frequencies are too low or too high for a successful calibration.

1995 mar 21 56 philips semiconductors preliminary speci?cation audio processor for vhs hi-? and linear audio TDA9614H 12.1 raf i/o (pin 12) the status of the i 2 c raf bit is output (raf = high; record). this output can be used to switch the audio fm head amplifier to playback and record. if accurate fast switching of the TDA9614H is needed, this pin can also be used as input. thereby overruling the i 2 c raf bit. to make this possible the raf output is current limited. when using the raf pin as output, no more than 35 m a (low) and 185 m a (high) current may be drawn from this pin to assure that the mode of the TDA9614H is not changed. when using the raf pin as input, the voltage source used must be capable of delivering at least 345 m a (forced high; > 3.5 v) or sinking at least 65 m a (forced low; < 1.5 v). 12.2 rccol, rccor, rbpf and rfix (pins 59, 53, 55 and 49) the external resistors to ground at pins rccol, rccor, rbpf and rfix must have a tolerance of 5%. this is necessary to guarantee correct functioning of the ic. the temperature coefficient of the external resistors at rccol, rccor and rbpf have a direct influence on the related frequencies of the on-chip oscillators and bandpass filters.

1995 mar 21 58 philips semiconductors preliminary speci?cation audio processor for vhs hi-? and linear audio TDA9614H 14 soldering 14.1 plastic quad ?at packages 14.1.1 b y wave during placement and before soldering, the component must be fixed with a droplet of adhesive. after curing the adhesive, the component can be soldered. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder bath is 10 s, if allowed to cool to less than 150 c within 6 s. typical dwell time is 4 s at 250 c. a modified wave soldering technique is recommended using two solder waves (dual-wave), in which a turbulent wave with high upward pressure is followed by a smooth laminar wave. using a mildly-activated flux eliminates the need for removal of corrosive residues in most applications. 14.1.2 b y solder paste reflow reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the substrate by screen printing, stencilling or pressure-syringe dispensing before device placement. several techniques exist for reflowing; for example, thermal conduction by heated belt, infrared, and vapour-phase reflow. dwell times vary between 50 and 300 s according to method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 min at 45 c. 14.1.3 r epairing soldered joints ( by hand - held soldering iron or pulse - heated solder tool ) fix the component by first soldering two, diagonally opposite, end pins. apply the heating tool to the flat part of the pin only. contact time must be limited to 10 s at up to 300 c. when using proper tools, all other pins can be soldered in one operation within 2 to 5 s at between 270 and 320 c. (pulse-heated soldering is not recommended for so packages.) for pulse-heated solder tool (resistance) soldering of vso packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement.
