General Description
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 150 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.
