general description the max9517/max9524 evaluation kits (ev kits) arefully assembled and tested surface-mount pcbs that evaluate the max9517 and the max9524 ics. both ics filter, amplify, and set the sync-tip level for standard- definition video signals. the ics feature an internal reconstruction filter that has 40db attenuation at 27mhz, and ?db passband flat- ness at 7mhz. the max9517 and max9524 have a 2v/v gain and are capable of driving 75 to ground. the ics feature two analog switches that are used toroute audio, video, or digital signals. video signals are dc-coupled to the input of the max9517 and ac-coupled to the input of the max9524. the max9524 features an input sync-tip clamp to set the dc level for the video signal. the ev kits?input ter- minal has 75 termination to ground. the ev kits?out- put has a 75 back-termination resistor. the ev kits operate from a single 2.7v to 3.6v power supply. features ? single 2.7v to 3.6v supply operation ? dc-coupled input (max9517) ? ac-coupled input with sync-tip clamp (max9524) ? 1db passband at 7mhz reconstruction filter with 40db attenuation at 27mhz ? preset gain of 2v/v ? drives 75 to ground ? small 12-pin thin qfn package ? fully assembled and tested evaluate: max9517/max9524 max9517/max9524 evaluation kits ___________________________________________________ _____________ maxim integrated products 1 19-0783; rev 0; 3/07 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information part temp range ic package MAX9517EVKIT + 0? to +70?* 12 thin qfn-ep**(3mm x 3mm) max9524evkit + 0? to +70?* 12 thin qfn-ep**(3mm x 3mm) part selection table part input coupling output coupling max9517atc+ dc dc max9524atc+ ac with sync-tip clamp dc + denotes a lead-free and rohs-compliant ev kit. * this limited temperature range is for the ev kit pcb only. the max9517 and max9524 ic temperature range is -40? to +125?. ** ep = exposed paddle. component list designation qty description c1 1 10? ?0%, 6.3v x5r ceramiccapacitor (0603) murata grm188r60j106m c2 1 0.1? ?0%, 25v x7r ceramiccapacitor (0603) tdk c1608x7r1e104k c3 1 see the ev kit-specific component list com1, com2, in, no1, no2, out 675 bnc pcb mount connectors ju1, ju2, ju3 3 3-pin headers r1, r2 2 75 ?% resistors (0603) r3 1 see the ev kit-specific component list r4?7 0 not installed, resistors (0603) u1 1 see the ev kit-specific component list 3 shunts ? pcb: max9517/max9524 evaluationkits+ ev kit reference designator description c3 not installed, capacitor(0603) r3 0 ?% resistor (0603) MAX9517EVKIT+ u1 max9517atc+ (12-pin,3mm x 3mm thin qfn with ep) c3 0.1? ?0%, 25v x7r,ceramic capacitor (0603) tdk c1608x7r1e104k r3 not installed, resistor(0603) max9524evkit+ u1 max9524atc+ (12-pin,3mm x 3mm thin qfn with ep) ev kit-specific component list downloaded from: http:///
