Maxim MAX7443/MAX7444 Triple-Channel Video Reconstruction Filter Datasheet
The MAX7443 and MAX7444 are low‑cost, triple‑channel video reconstruction filters and buffers designed for composite (CVBS) and Y/C (S‑Video) signals. They are optimized for NTSC, PAL, and standard‑definition digital TV applications such as set‑top boxes, DVD players, hard‑disk recorders, and digital VCRs, operating from a single +5 V supply.
Key specifications include a typical stopband attenuation of 41 dB at 27 MHz, a passband response of –0.3 dB (typ), and adjustable output gain of 6 dB, 9.5 dB, or 12 dB. The devices are offered in tiny 8‑pin thin QFN or 8‑pin SO packages with exposed pads, each channel capable of driving two 150 Ω video loads.
