Description

The MAX7446 4-channel, buffered video reconstruction filter is ideal for anti-aliasing and DAC-smoothing video applications or wherever analog video is reconstructed from a digital data stream (such as cable/satellite/terrestrial set top boxes, DVD players, hard disk recorders (HDRs), and personal video recorders (PVRs)). This MAX7446 operates from a single +5V supply and has a flat passband out to 5MHz with a stopband attenuation of 43dB at 27MHz. This makes it ideal for use with NTSC, PAL, and standard-definition digital TV (SDTV) video systems. Each output of MAX7446 is capable of driving two standard 150 video loads.

The MAX7446 processes CVBS and RGB video signals. The video output buffers have a fixed gain of +6dB. The channel for CVBS video has high-frequency boost circuitry that provides picture sharpness with +1.2dB of gain boost without degradation in the stopband. The output video drivers MAX7446 can be disabled with an external pin.

The MAX7446 is available in a 14-pin TSSOP package with an exposed pad, and is specified over the -40°C to +85°C extended temperature range
