Triple-Channel HDTV Filters
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 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/SMPTE274M 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 16-pin SO and compact 16-pin QSOP packages, and are fully specified over the -40C to +85C extended temperature range.

Output Buffer
The MAX9500/MAX9501 output buffers provide +6dB of gain and can drive 2VP-P into a single or double back-terminated load (150 or 75, respectively) directly to ground. The output can be AC-coupled or DC-coupled.
MAX9500/MAX9501
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.

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.
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.
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.
