MAX7446 4-Channel Video Filter For RGB And CVBS VideoThe 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 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 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 -40C to +85C extended temperature range. By Maxim Integrated Products |
