The MAX7443/MAX7444 are low-cost, triple-channel

video reconstruction filters for S-video and CVBS video

signals. These devices are ideal for anti-aliasing and

DAC smoothing video applications such as set-top

boxes, DVD players, hard-disk recorders (HDRs), and

personal video recorders. These filters operate from a

single +5V supply. They are optimized for NTSC, PAL,

and standard-definition digital TV (SDTV) video systems.

Each channel consists of a lowpass filter and an

adjustable-gain output buffer capable of driving two

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 com-

posite video output. The MAX7444 offers high-

frequency boost to improve picture sharpness. The

MAX7443 has a maximum flat-frequency response.

The MAX7443/MAX7444 are available in a tiny 8-pin thin

QFN and an 8-pin SO package with exposed pad, and

are fully specified over the -40°C to +85°C extended

temperature range.
