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 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 –40°C to +85°C extended temperature range.
