Description
The MAX7453 is a low-cost, triple-channel video reconstruction filter for S-video and CVBS video-signal applications. 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-definition 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 blanking 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 maximally 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) temperature range.
