MAX7445 4-Channel Video Reconstruction Filter

The MAX7445 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 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 150 Video loads.
The MAX7445 has three modes of operation. Mode 1 processes CVBS and RGB Video signals. Mode 2 processes CVBS, Y, and C signals, as well as a second asynchronous CVBS Video signal. Mode 3 processes RGB and CVBS (asynchronous) Video signals. An external pin adjusts the gain of the Video Buffer to either +6dB, +9.5dB, or +12dB to accommodate video-encoder DAC output signals of < 1V. High-frequency boost circuitry 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 MAX7445 is available in a 14-pin TSSOP package with an exposed pad, and is specified over the -40C to +85C extended temperature range.
