general description the max9503 filters and amplifies standard-definition video signals. maxim? directdrive technology elimi- nates large output-coupling capacitors and sets the video black level to ground. the input of the max9503 can be directly connected to the output of a video digital -to-analog converter (dac). the max9503 pro- vides a compact, integrated, and low-power solution. an internal reconstruction filter smoothes the steps and reduces the spikes on the video signal from the dac. the reconstruction filter typically has 3db attenuation at 9mhz and 50db attenuation at 27mhz, and ?db pass- band flatness to 5.5mhz. maxim? directdrive uses an integrated charge pump and a linear regulator to create a clean negative power supply to drive the sync below ground. the charge pump injects so little noise into the video output that the picture is visibly flawless. the max9503 is available with +6db (max9503g) and +12db (max9503m) gains. the device operates from a 2.7v to 3.6v single supply and features a 10na low- power shutdown mode. the max9503 is offered in space-saving 16-pin qsop and 16-pin tqfn packages and is specified over the -40? to +85? extended temperature range. applications digital still cameras mobile phones/smartphones security cameras portable media players space-constrained, low-power portable devices features ? dc-coupled output ? direct connection to video dac ? video output black level set to ground ? video reconstruction filter with 50db attenuation at 27mhz ? preset gain 6db (max9503g) 12db (max9503m) ? 10na shutdown supply current ? 2.7v to 3.6v single-supply operation max9503 directdrive video amplifier with reconstruction filter ________________________________________________________________ maxim integrated products 1 ordering information 0 to 50mv 0v -0.1v to +0.1v max9503 amp linear regulator charge pump buffer vidout vidin max9503g: 6db max9503m: 12db lowpass filter 0v 19-3676; rev 0; 5/05 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part* pin- package pkg code top mark max9503geee 16 qsop e16-4 max9503gete 16 tqfn t1633-4 acu max9503meee 16 qsop e16-4 MAX9503METE 16 tqfn t1633-4 acv functional diagram/typical operating circuit and pin configurations appear at end of data sheet. * all devices are specified over the -40? to +85? operating temperature range. block diagram

max9503 detailed description the max9503 completely eliminates the need for capacitors in the video output by using maxim? directdrive technology that includes an inverting charge pump and linear regulator. the charge pump and linear regulator create a clean negative supply allowing the amplifier output to swing below ground. the amplifier output can swing both positive and negative so that the video signal black level can be placed at ground. the max9503 features a six-pole, butterworth filter to per- form reconstruction filtering on the video input signal from the dac. directdrive background integrated video filter/amplifier circuits operating from a single, positive supply usually create video output sig- nals that are level-shifted above ground to keep the signal within the linear range of the output amplifier. for applications in which the positive dc level shift of the video signal is not acceptable, a series capacitor can be inserted in the output connection in an attempt to eliminate the positive dc level shift. the series capaci- tor cannot truly level shift a video signal because the average level of the video varies with picture content. the series capacitor biases the video output signal around ground, but the actual level of the video signal can vary significantly depending upon the rc time con- stant and the picture content. the series capacitor creates a highpass filter. since the lowest frequency in video is the frame rate, which can be between 24hz and 30hz, the pole of the high- pass filter should ideally be an order of magnitude lower in frequency than the frame rate. therefore, the series capacitor must be very large, typically from 220? to 3000?. for space-constrained equipment, the series capacitor is unacceptable. changing from a single series capacitor to a sag network that requires two smaller capacitors can only reduce space and cost slightly. the series capacitor in the usual output connection also prevents damage to the output amplifier if the con- nector is shorted to a supply or to ground. while the output connection of the max9503 does not have a series capacitor, the max9503 will not be damaged if the connector is shorted to a supply or to ground (see the short-circuit protection section). video amplifier typically, the black level of the video signal created by the video dac is around 300mv. the max9503 shifts the black level to ground at the output so that the active video is above ground, and sync is below ground. the amplifier needs a negative supply for its output stage to remain in its linear region when driving sync below ground. directdrive video amplifier with reconstruction filter 8 _______________________________________________________________________________________ pin description pin qsop tqfn name function 115v ss negative power supply. connect to cpv ss . 216 cpv ss charge-pump negative power supply. bypass with a 1? capacitor to cpgnd. 31 c1n charge-pump flying capacitor negative terminal. connect a 1? capacitor from c1p to c1n. 42 cpgnd charge-pump power ground 53 c1p charge-pump flying capacitor positive terminal. connect a 1? capacitor from c1p to c1n. 64 cpv dd charge-pump positive power supply. bypass with a 1? capacitor to cpgnd. 75 bias common-mode voltage. connect a 100k ? resistor from bias to sgnd. 86 sgnd signal ground. connect to gnd. 97 vidin video input 10, 14, 15 8, 12, 14 n.c. no connection. not internally connected. connect to sgnd. 11 9 shdn active-low shutdown. connect to v dd for normal operation. 12 10 gnd ground. connect to sgnd. 13 11 v dd positive power supply. bypass with a 1? capacitor to sgnd. 16 13 vidout video output ? pe p exposed paddle. connect to gnd.
the max9503 has an integrated charge pump and linear regulator to create a low-noise negative supply from the positive supply voltage. the charge pump inverts the positive supply to create a raw negative voltage that is then fed into the linear regulator, which outputs -2v. the linear regulator filters out the charge-pump noise. comparison between directdrive output vs. ac-coupled output the actual level of the video signal varies less with a directdrive output than an ac-coupled output. the video signal average can change greatly depending upon the picture content. with an ac-coupled output, the average will change according to the time constant formed by the series capacitor and series resistance (usually 150 ? ). for example, figure 1 shows an ac- coupled video signal alternating between a completely black screen and a completely white screen. notice the excursion of the video signal as the screen changes. with the directdrive amplifier, the black level is held at ground. the video signal is constrained between -0.3v to +0.7v. figure 2 shows the video signal from a directdrive amplifier with the same input signal as the ac-coupled system. video reconstruction filter before the video signal from the dac can be amplified, it must be lowpass filtered to smooth the steps and to reduce the spikes created whenever the dac output changes value. in the frequency domain, the steps and spikes cause images of the video signal to appear at multiples of the sampling clock. the max9503 contains a six-pole butterworth lowpass filter. the passband extends to 5.5mhz, and the minimum attenuation is 35db at 27mhz. short-circuit protection the max9503 typical application circuit includes a 75 ? back-termination resistor that limits short-circuit current if an external short is applied to the video output. the max9503 features internal output, short-circuit protection to prevent device damage in prototyping and applica- tions where the amplifier output can be directly shorted. shutdown the max9503 features a low-power shutdown mode for battery-powered/portable applications. shutdown reduces the quiescent current to less than 10na. connecting shdn to ground (sgnd) disables the out- puts and places the max9503 into a low-power shut- down mode. in shutdown mode, the amplifier, charge pump, and linear regulator are turned off and the video output impedance is 4k ? . max9503 directdrive video amplifier with reconstruction filter _______________________________________________________________________________________ 9 input 500mv/div output 500mv/div 2ms/div figure 1. ac-coupled output input 500mv/div output 1v/div 2ms/div 0v 0v figure 2. directdrive output
max9503 applications information power-supply bypassing and ground management the max9503 operates from a 2.7v to 3.6v single sup- ply and requires proper layout and bypassing. for the best performance, place the components as close to the device as possible. proper grounding improves performance and prevents any switching noise from coupling into the video signal. connect gnd and sgnd together at a single point on the pc board. route all traces that carry switching tran- sients away from sgnd. return sgnd to the lowest impedance ground available. route cpgnd and all traces carrying switching transients away from sgnd, gnd, and other traces and components in the video signal path. bypass the analog supply (v dd ) with a 1? capacitor to sgnd, placed as close to the device as possible. bypass the charge-pump supply (cpv dd ) with a 1? capacitor to cpgnd, placed as close to the device as possible. connect cpv ss to v ss and bypass with a 1? capacitor to cpgnd as close to the device as possible. directdrive video amplifier with reconstruction filter 10 ______________________________________________________________________________________ 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 v ss vidout n.c. n.c. v dd gnd shdn n.c. vidin qsop cpv ss c1n cpv dd cpgnd c1p bias sgnd max9503 12 13 14 15 16 8 7 6 5 11 10 9 1234 n.c. v dd gnd shdn n.c. vidin sgnd bias n.c. v ss cpv ss c1n cpgnd c1p cpv dd vidout top view max9503 3mm x 3mm tqfn pin configurations
