19-3779; Rev 4; 1/07 KIT ATION EVALU E L B A IL AVA Triple-Channel HDTV Filters 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 5V 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 currentoutput, 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/SMPTE 274M filter template achieving > 40dB attenuation at 44.25MHz. The MAX9500/MAX9501 can also be used as an antialiasing filter for HDTV component inputs. The MAX9500/MAX9501 are available in compact 16-pin QSOP packages and are fully specified over the -40C to +85C extended temperature range.

The output can be AC-coupled or DC-coupled. Applications Information Input Considerations The MAX9500/MAX9501 inputs are normally DC-coupled. 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, current-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. Pr Channel Output Positive Supply PbOUT Pb Channel Output 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 5V 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 lowpass filters to remove out-of-band noise, and a gain of +6dB in the output amplifier to drive 75 back-terminated 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 Considerations The MAX9500/MAX9501 outputs are normally DC-coupled, 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 5V supplies. Bypass VCC and VEE (MAX9501) to GND with a 0.1F capacitor as close to the device as possible, and an additional 1F 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 performance 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 capacitance and noise pickup. _______________________________________________________________________________________ 7 MAX9500/MAX9501 Pin Description Triple-Channel HDTV Filters MAX9500/MAX9501 Pin Configurations TOP VIEW SUBG 1 YIN 2 16 SUBG VEE 1 16 VEE 15 VCC YIN 2 15 VCC 14 YOUT GND 3 MAX9500 14 YOUT GND 3 MAX9501 PbIN 4 13 VCC PbIN 4 13 VCC GND 5 12 PbOUT GND 5 12 PbOUT PrIN 6 11 VCC PrIN 6 11 VCC SUBG 7 10 PrOUT VEE 7 10 PrOUT SUBG 8 9 VEE 8 9 SUBG QSOP VEE QSOP Chip Information PROCESS: Bipolar 8 _______________________________________________________________________________________ Triple-Channel HDTV Filters QSOP.EPS PACKAGE OUTLINE, QSOP .150", .025" LEAD PITCH 21-0055 F 1 1 Revision History Pages changed at Rev 4: 1, 2, 3, 9 Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
