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 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 75Ω 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 anti-
aliasing filter for HDTV component inputs.
The MAX9500/MAX9501 are available in compact 16-pin
QSOP packages and are fully specified over the -40°C to
+85°C extended temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
