general description the max9586?ax9589 are small, low-power, multi-channel video amplifiers with integrated reconstruction filters and input clamps. specially suited for standard- definition video signals, these devices are ideal for a wide range of television and set-top box applications. the video signals from the outputs of a digital-to-analog converter (dac) are ac-coupled to the inputs of the max9586?ax9589. external video signals, in which the dc bias is usually not known, can also be ac-cou- pled to the inputs of the max9586?ax9589. the input sync-tip clamps set the dc level of composite video or luma signals, and the input bias circuits set the dc level of chroma signals. the reconstruction filter typically has ?db passband flatness at 8.5mhz and 55db attenuation at 27mhz. the amplifiers have 2v/v gain and the outputs can be dc- coupled to a 75 load, which is the equivalent of two video loads, or ac-coupled to a 150 load. the max9586?ax9589 operate from a 2.7v to 3.6v sin-gle supply and are specified over the -40? to +125? automotive temperature range. the max9586?ax9589 are offered in small sot23 and ?ax packages. applications set-top boxestelevisions features ? single- (max9586), dual- (max9587), triple- (max9588), and quad- (max9589) channel devices ? 8.5mhz, ?db passband ? 55db attenuation at 27mhz ? fixed gain of 2v/v ? low power: 4.25ma per channel ? 2.7v to 3.6v single-supply operation ? small sot23 and max packages max9586?ax9589 single, dual, triple, and quad standard-definition video filter amplifiers with ac-coupled input buffers ________________________________________________________________ maxim integrated products 1 ina outa lpf a v = 2v/v max9588 unknown bias 300mv clamp inb outb lpf a v = 2v/v clamp inc outc lpf a v = 2v/v bias block diagrams 19-0744; rev 6; 2/11 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. evaluation kit available ?ax is a registered trademark of maxim integrated products, inc. ordering information note: all devices are specified over the -40? to +125? operat- ing temperature range. + denotes a lead(pb)-free/rohs-compliant package. t = tape and reel. part pin-package channels max9586 azk+t 5 thin sot23 1 max9587 azt+t 6 thin sot23 2 max9588 aua+t 8 ?ax 3 max9589 aub+t 10 ?ax 4 block diagrams continued at end of data sheet. pin configurations and selector guide located at end of data sheet. downloaded from: http:///

max9586?ax9589 single, dual, triple, and quad standard-definition video filter amplifiers with ac-coupled input buffers _______________________________________________________________________________________ 9 detailed description the max9586?ax9589 filter and amplify the videodac output in applications such as set-top boxes and televisions. these devices consist of input clamps, input bias circuits, lowpass filters, and gain of 2v/v out- put amplifiers capable of driving a standard 150 ? video load to ground. inputs the input stages of the max9586?ax9589 are eithersync-tip clamps or bias circuits. sync-tip clamps accept ac-coupled cvbs or luma video signals with sync puls- es. the sync-tip voltage is internally set to 300mv. bias circuit inputs accept ac-coupled chroma, a subcarrier modulated with the color information. the bias voltage of the bias circuits is approximately 500mv. video filter the filter passband (?db) is typically 8.5mhz, whichmakes the device suitable for standard-definition video signals from all sources (e.g., broadcast and dvd). broadcast video signals are channel limited: ntsc sig- nals have 4.2mhz bandwidth and pal signals have 5mhz bandwidth. video signals from a dvd player, however, are not channel limited, so the bandwidth of dvd video signals can approach the nyquist limit of 6.75mhz. (recommendation itu-r bt.601-5 specifies 13.5mhz as the sampling rate for standard-definition video). therefore, the maximum bandwidth of the signal is 6.75mhz. to ease the filtering requirements, most modern video systems oversample by two times, clock- ing the video current dac at 27mhz. outputs the video output amplifiers can both source and sinkload current, allowing output loads to be dc- or ac- coupled. the amplifier output stage needs approxi- mately 300mv of headroom from either supply rail. the devices have an internal level-shift circuit that positions the sync tip at approximately 300mv at the output. if the supply voltage is greater than 3.135v (5% below a 3.3v supply), each amplifier can drive two dc-cou- pled video loads to ground. if the supply is less than 3.135v, each amplifier can drive only one dc-coupled or ac-coupled video load. shutdown (max9586) the max9586 draws less than 1? supply currentwhen shdn is low. in shutdown mode, the amplifier output becomes high impedance. applications information ac-coupling the outputs the outputs can be ac-coupled since the output stagecan source and sink current as shown in figure 4. coupling capacitors should be 220? or greater to keep the highpass filter, formed by the 150 ? equivalent resistance of the video transmission line, to a cornerfrequency of 4.8hz or below. the frame rate of pal systems is 25hz, and the frame rate of ntsc systems is 30hz. the corner frequency should be well below the frame rate. power-supply bypassing and ground the max9586?ax9589 operate from a single-supplyvoltage down to 2.7v, allowing for low-power operation. bypass v dd to gnd with a 0.1? capacitor. place all external components as close as possible to the device. cvbs in loopback out 37.5 75 0.1 f v in dout 37.5 max9526 0.1 f in out max9586 figure 3. loopback circuit diagram downloaded from: http:///
