MAX7443/MAX7444 19-2749; Rev 0; 1/03 Triple-Channel Video Reconstruction Filter and Buffer for Composite and Y/C Outputs 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 fo.

MAX7443/MAX7444 19-2749; Rev 0; 1/03 Triple-Channel Video Reconstruction Filter and Buffer for Composite and Y/C Outputs 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 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 MAX7444 offers highfrequency boost to improve picture sharpness. The MAX7443 has a.
