11 fn6233.3 september 26, 2006 description of operat ion and application information theory of operation the isl59830a is a highly practical and robust marriage of three high bandwidth, high speed, low power, rail-to-rail voltage feedback amplifiers with a charge pump, to provide a negative rail without an additional power supply. designed to operate with a single supply voltage range of from 0v to 3.3v, the isl59830a eliminates the need for a split supply with the incorporation of a charge pump capable of generating a bottom rail as much as 1.6v below ground; for a 4.9v range on a single 3.3v supply. this performance is ideal for ntsc video with its negative-going sync pulses. the amplifier the isl59830a fabricated on a dielectrically isolated high speed 5v bi-cmos process with 4ghz pnps and npn transistor exceeding 20ghz - pe rfect for low distortion, low power demand and high frequency circuits. while the isl59830a utilizes somewhat standard voltage mode feedback topologies, there are many non-standard analog features providing its outstanding bandwidth, rail-to-rail operation, and output drive ca pabilities. the input signal initially passes through a folded cascode, a topology providing enhanced frequency response essentially by fixing the base collector voltage at the junction of the input and gain stage. the collector of eac h input device looks directly into an emitter that is tied closely to ground through a resistor and biased with a very stable dc source. since the voltage of this collector is "locked stable" the effective bandwidth limiting of the miller capacitance is greatly reduced. the signal is then passed through a second fully- realized differential gain stage and finally through a proprietary common emitter output stage for improved rail- to-rail output performance. the re sult is a highly-stable, low distortion, low power, and high frequency amplifier capable of driving moderately capacitive loads with near rail-to-rail performance. input output range the three amplifier channels have an input common mode voltage range from 0.15v below the bottom rail to within 100mv of the positive supply, v s + pin (note: bottom rail is established by the charge pu mp at negative one half the positive supply). as the input signal moves outside the specified range, the output sign al will exhibit increasingly higher levels of harmonic dist ortion. and of course, as load resistance becomes lower, the current drive capability of the device will be challenged and its ability to drive close to each rail is reduced. for instance, with a load resistance of 1k ? the output swing is within 100mv of the rails, while a load resistance of 150 ? limits the output swing to within around 300mv of the rails. amplifier output impedance to achieve near rail-to-rail per formance, the output stage of the isl59830a uses transistors in the common emitter configuration, typically pro ducing higher output impedance than the standard emitter fo llower output stage. the exceptionally high open loop gain of the isl59830a and local feedback reduces output impedance to less than 2 ? at low frequency. however, since output impedance of the device is exponentially modulated by the magnitude of the open loop gain, output impedance increases with frequency as the open loop gain decreases with frequency. this inductive-like effect of the outp ut impedance is countered in the isl59830a with proprieta ry output stage topology, keeping the output impedance low over a wide frequency range and making it possible to easily and effectively drive relatively heavy capacitive loads (see figure 10). i n + i n - bias out figure 27. isl59830a
12 fn6233.3 september 26, 2006 the charge pump the isl59830a charge pump provides a bottom rail up to 1.65v below ground while operating on a 0v to 3.3v power supply. the charge pump is internally regulated to one-half the potential of the positive supply. this internal multi-phase charge pump is driven by a 160mhz differential ring oscillator driving a series of inverters and charge storage circuitry. each series inverter charges and places parallel adjoining charge circuitry slightly out of phase with the immediately preceding block. the overall effect is sequential discharge and generation of a very low ripple of about 10mv that is applied to the amplifiers providing a negative rail of up to -1.65v. there are two options to reduc e the output supply noise. ? add a 120 ? bead in series between v cc and dv cc to further reduce ripple. ? add a 20pf capacitor between the back load 75 ? resistor and ground (see the isl59830a + dc-restore solution schematic on page 10). the system operates at sufficie ntly high frequencies that any related charge pump noise is far beyond standard video bandwidth requirements. still, appropriate bypassing discipline must be observed, and all pins related to either the power supply or the charge pump must be properly bypassed. see "power supply bypassing and printed circuit board layout" in this section. the v ref pin applying a voltage to the vref pin simply places that voltage on what would usually be the ground side of the gain resistor of the amplifier, resu lting in a dc-level shift of the output signal. applying 100mv to the vref pin would apply a 100mv dc level shift to the outgoing signal. the charge pump provides sufficient bottom room to accommodate the shifted signal. note: the vref input is the common point of the 3 amps minus input resistors. any common resistance on vref input will share the voltage induc ed on it with all the other amps, so using a resistor source to get offset will cause cross talk and gain change for the offset for all amps and amp +input gain change. offset on the vref pin must be low impedance to prevent gain error and cross talk. a transistor emitter follower should work like an npn mmbt3904 with the emitter conn ected to the vref pin and 1k pull down to v- with 1f cap bypass to ground and the collector to v+ and base to v offset source. if better tempco is needed then a diode may be used in series with the pot to ground. a 499w resistor may be added in series with the collector to prevent damage when testing. see the block diagram on page 9. the v ee pin the v ee pin is the output pin for the charge pump. a voltmeter applied to this pin will display the output of the charge pump. this pin does not af fect the functionality of the part. one may use this pin as an additional voltage source. keep in mind that the output of this pin is generated by the internal charge pump and a fully regulated supply that must be properly bypassed. we recommend a 0.1f ceramic capacitor placed as close to the pin and connected to the ground plane of the board. input, output, and supply voltage range the isl59830a is designed to operate with a single supply voltage range of from 0v to 3.3v. the need for a split supply has been eliminated with the in corporation of a charge pump capable of generating a bottom rail as much as 1.6v below ground, for a 4.9v range on a single 3.3v supply. this performance is ideal for ntsc video with its negative-going sync pulses. video performance for good video performance, an amplifier is required to maintain the same output impedance and the same frequency and phase response as dc levels are changed at the output. this is especially difficult when driving a standard video load of 150 ? because of the change in output current with changing dc levels. special ci rcuitry has been incorporated into the isl59830a for the r eduction of output impedance variation with the current output. this results in outstanding differential gain and differential phase specifications of 0.06% and 0.1, while driving 150 ? at a gain of +2. driving higher impedance loads would result in similar or better differential gain and differential phase performance. ntsc the isl59830a, generating a negative rail internally, is ideally suited for ntsc video with its accompanying negative-going sync signals; easily handled by the isl59830a without the need of an additional supply as the isl59830a generates a negative rail with an internal charge pump referenced at negative 1/2 the positive supply. ypbpr ypbpr signals originating from a dvd player requiring three channels of very tightly-controlled amplifier gain accuracy present no difficulty for the isl59830a. specifically, this volts (10mv/div) time (20ns/div) figure 28. charge pu mp oscillation isl59830a
13 fn6233.3 september 26, 2006 standard encodes sync on the y channel and it is a negative- going signal; easily handled by the isl59830a without the need of an additional supply as t he isl59830a generates a negative rail placed at negative 1/2 the positive supply. additionally, the pb and pr are bipolar analog signals and the video signals are negative-going; and again easily handled by the isl59830a. driving capacitive loads and cables the isl59830a, internally-c ompensated to drive 75 ? cables, will drive 10pf loads in parallel with 1k ? with less than 5db of peaking. if less peaking is required, a small series resistor, usually between 5 ? to 50 ? , can be placed in series with the output. this will reduce peaking at the expense of a slight closed loop gain reduction. when used as a cable driver, double termination is always recommended for reflection-free performance. for those applicati ons, a back-termination series resistor at the amplifier's output will isolate the amplifier from the cable and allow extensive capa citive drive. however, other applications may have high capacitive loads without a back- termination resistor. again, a sma ll series resistor at the output can help to reduce peaking. the isl59830a is a triple amplifier designed to drive three channels; simply deal with each channel separately as described in this section. dc-restore when the isl59830a is ac-coupled it becomes necessary to restore the dc reference for the signal. this is accomplished with a dc-restore system applied between the capacitive "ac" coupling and the input of the device. refer to application circuit for re ference dc-restore solution. disable/power-down the isl59830a can be disabled and its output placed in a high impedance state. the turn-off time is around 25ns and the turn-on time is around 200ns. when disabled, the amplifier's supply current is reduced to 0.9ma typically, thereby effectively eliminating the power consumption. the amplifier's power-down can be controlled by standard ttl or cmos signal levels at the en and pd pins. the applied logic signal is relative to v s - pin. letting the en and pd pins float or applying a signal that is less than 0.8v above v s - will enable the amplifier. the amplifier will be disabled when the signal at en pin is 2v above v s -. the amplifier must be disabled (en pin is high) whenever the charge pump is disabled (pd pin is high). en and pd pins should be connected together to allow amplifier and charge pump to enable/disable simultaneously. output drive capability the isl59830a does not have internal short-circuit protection circuitry. a short-circuit current of 80ma sourcing and 150ma sinking for the output is connected to half way between the rails with a 10 ? resistor. if the output is shorted indefinitely, the power dissipation could easily increase such that the part will be destroyed. maximum reliability is maintained if the output current never exceeds 40ma, after which the electro-migration limit of the process will be exceeded and the part will be damaged. this limit is set by the design of the internal metal interconnections. power dissipation with the high output drive capabi lity of the isl59830a, it is possible to exceed the +150c absolute maximum junction temperature under certain load current conditions. therefore, it is im portant to calculate the maximum junction temperature for an application to determine if load conditions or package types need to be modified to assure operation of the amplifier in a safe operating area. the maximum power dissipation allowed in a package is determined according to: where: t jmax = maximum junction temperature t amax = maximum ambient temperature ja = thermal resistance of the package the maximum power dissipation actually produced by an ic is the total quiescent supply current times the total power supply voltage, plus the power in the ic due to the load, or: for sourcing: for sinking: where: v s = supply voltage i smax = maximum quiescent supply current v out = maximum output voltage of the application r load = load resistance tied to ground i load = load current i = number of output channels by setting the two p dmax equations equal to each other, we can solve the output current and r load to avoid the device overheat. pd max t jmax t amax ? ja -------------------------------------------- - = pd max v s i smax v s v out i ?

14 fn6233.3 september 26, 2006 power supply bypassing and printed circuit board layout strip line design techniques are recommended for the input and output signal traces. as with any high frequency device, a good printed circuit board layout is necessary for optimum performance. lead lengths should be as short as possible. the power supply pin must be well bypassed to reduce the risk of oscillation. for normal single supply operation, where the v s - pin is connected to the ground plane, a single 4.7f tantalum capacitor in parallel with a 0.1f ceramic capacitor from v s + to gnd will suffice. this same capacitor combination should be placed at each supply pin to ground if split-internal supplies are to be used. in this case, the v s - pin becomes the negative supply rail. for good ac performance, parasitic capacitance should be kept to a minimum. use of wi re-wound resistors should be avoided because of their additional series inductance. use of sockets should also be avoided if possible. sockets add parasitic inductance and capacitance can result in compromised performanc e. minimizing parasitic capacitance at the amplifier's inverting input pin is also very important. isl59830a
