MAXIM MAX7446 handbook
Update: 30 September, 2023
The MAX7446 is a 4-channel, buffered video reconstruction filter ideal for anti-aliasing and DAC-smoothing video applications or wherever analog video is reconstructed from a digital data stream (such as cable/satellite/ter- restrial set-top boxes, DVD players, hard disk recorders (HDRs), and personal video recorders (PVRs)). This device 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 is capable of driving two standard 150Ω 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 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. Applications: Set-Top Boxes/HDRs Game Consoles Desktop Video Editors DVD Players Digital VCRs
