The MAX7453 is a low-cost, triple-channel video recon-
struction filter for S-video and CVBS video-signal appli-
cations. This device is ideal for anti-aliasing and DAC
smoothing video applications such as set-top boxes,
DVD players, hard-disk recorders (HDRs), and personal
video recorders. This filter operates from a single +5V
supply. It is optimized for NTSC, PAL, and standard-defi-
nition TV (SDTV) video systems.
Each channel consists of a lowpass filter and an output
buffer capable of driving one (YOUT, COUT) or two
(CVOUT) standard 150Ω video loads. The output buffers
can drive either an AC or a DC load such that the blank-
ing level voltage after the backmatch resistor is less than
1V. The Y and C video inputs are summed to produce
the composite video output. The MAX7453 has a maxi-
mally flat frequency response.
The MAX7453 is available in an 8-pin SO package and is
fully specified over the commercial (0°C to +70°C) tem-
perature range.
