general description the MAX9500/max9501 are fully integrated solutions for filtering and buffering hdtv signals. the MAX9500 operates from a single +5v supply, while the max9501 operates from dual ?v supplies. the MAX9500/ max9501 triple-channel video reconstruction filters are both gain and delay matched and are ideal for use in set-top boxes, dvd players, and other equipment that generate analog hdtv outputs. the MAX9500/max9501 interface between the current- output, digital-to-analog converters (dac) of an advanced television standard committee (atsc), motion picture experts group (mpeg) decoder and the external connections of a television, set-top box, or dvd player. the MAX9500/max9501 feature a dc-coupled input with very low input capacitance and high resistance. the highly selective lowpass filters remove spectral replicas at the output of the dac. the output amplifier has +6db of gain to drive 75 ? back-terminated loads to unity gain. the dc-coupled input eliminates problems such as sync crush, droop, and field tilt. the output load can be dc- or ac-coupled, depending on the application. all three channels in the MAX9500/max9501 have the same frequency response with matched group delay and gain. the MAX9500/max9501 filter response meets the requirements of the eia-770.3/smpte274m filter template achieving > 40db attenuation at 44.25mhz. the MAX9500/max9501 can also be used as an anti- aliasing filter for hdtv component inputs. the MAX9500/max9501 are available in 16-pin so and compact 16-pin qsop packages, and are fully specified over the ?0? to +85? extended temperature range. applications cable and satellite set-top box receivers a/v receivers home theater systems hdtv sets dvd players video projectors digital displays features ? 30mhz bandwidth at ?.5db ? extremely sharp rolloff, lowpass filters -50db at 44.25mhz ? dc-coupled inputs; ac- or dc-coupled outputs ? ?v dual supply (max9501) ? 5v single supply (MAX9500) ? matched group delay and gain ? drive single/double back-terminated loads (150 ? /75 ? ) directly to ground ? sink and source output current ? high input impedance to interface to low output- current dac ? 16-pin so and qsop packages MAX9500/max9501 t riple-channel hdtv filters ________________________________________________________________ maxim integrated products 1 ordering information 19-3779; rev 1; 11/05 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 temp range pin- package supply voltage (v) MAX9500 ese+* -40? to +85? 16 so +5 MAX9500eee+ -40? to +85? 16 qsop +5 max9501 ese+* -40? to +85? 16 so ? max9501eee+* -40? to +85? 16 qsop ? pin configurations appear at end of data sheet. + denotes lead-free package. * future product?ontact factory for availability.

MAX9500/max9501 t riple-channel hdtv filters _______________________________________________________________________________________ 7 detailed description the MAX9500/max9501 are fully integrated solutions for filtering and buffering hdtv signals. the MAX9500 operates from a single +5v supply, while the max9501 operates from dual ?v supplies. the MAX9500/ max9501 interface between the current-output dacs of an atsc, mpeg decoder, and the external connections of a television, set-top box, or dvd player. the MAX9500/max9501 feature a dc-coupled input buffer with very low input capacitance, highly selective low- pass filters to remove out-of-band noise, and a gain of +6db in the output amplifier to drive 75 ? back-termi- nated loads to unity gain. the dc-coupled input buffer eliminates sync crush, droop, and field tilt. the output load can be dc- or ac-coupled. filter the MAX9500/max9501 reconstruction filters feature a 6th-order elliptical response, providing a 1.5db flat passband response up to 30mhz. the filter meets the selectivity requirements of the eia-770.3/smpte 274m filtering template, achieving > 40db attenuation at 44.25mhz. the MAX9500/max9501 can also be used as anti-aliasing filters for hdtv component inputs. output buffer the MAX9500/max9501 output buffers provide +6db of gain and can drive 2v p-p into a single or double back-ter- minated load (150 ? or 75 ? , respectively) directly to ground. the output can be ac-coupled or dc-coupled. applications information input considerations the MAX9500/max9501 inputs are normally dc-cou- pled. no ac-coupling capacitors are required because the input voltage range includes ground and extends up to 1.4v, allowing the MAX9500/max9501 to be directly connected to the output of a single-supply, cur- rent-output dac without any external bias network. the MAX9500/max9501 inputs can be ac-coupled. use a fixed bias or video clamp to set the dc bias to ensure that the negative peak of the video signal is as near to 0v as possible. a video clamp is preferred because it limits the total swing of the signal and holds the blanking level constant. output considerations the MAX9500/max9501 outputs are normally dc-cou- pled, so no ac-coupling capacitors are required. for 0v input, the MAX9500 output voltage is 0.8v and the max9501 output voltage is 0v, typical. connect the MAX9500/max9501 directly to a video cable with a 75 ? series back-termination resistor to match the impedance of the cable. properly terminate the other end of the cable with a 75 ? load. the MAX9500/max9501 outputs can sink and source current allowing the device to be ac-coupled. however, ac-coupling the outputs will degrade the tilt. power-supply bypassing and layout considerations the MAX9500 operates from a single +5v supply while the max9501 operates from dual ?v supplies. bypass v cc and v ee (max9501) to gnd with a 0.1? capacitor as close to the device as possible, and an additional 1? capacitor in parallel if any significant low-frequency disturbances are present in the vicinity of the MAX9500/max9501. use an extensive ground plane to ensure optimum performance. the input and output termination resistors should be placed as close to the device as possible to avoid per- formance degradation in the frequency response. the pc board traces at the output should have 75 ? characteristic impedance when matching into a 75 ? characteristic impedance cable. keep the board trace at the inputs and outputs of the MAX9500/max9501 as short as possible to minimize the parasitic stray capaci- tance and noise pickup. pin description pin MAX9500 max9501 name function 1, 7, 8, 9, 16 subg substrate ground. connect to ground. 22 yin y channel input 3, 5 3, 5 gnd ground 44 pbin pb channel input 66 prin pr channel input 10 10 prout pr channel output 11, 13, 15 11, 13, 15 v cc positive supply 12 12 pbout pb channel output 14 14 yout y channel output 1, 7, 8, 9, 16 v ee negative supply
