General Description
MAX7447 General Description
The MAX7447 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 MAX7447 processes S-Video and CVBS video signals. The video output buffers have a fixed gain of +6dB. Each channel has high-frequency boost circuitry that provides picture sharpness with up to +1.2dB of gain boost without degradation in the stopband. The output video drivers can be disabled with an external pin.
The MAX7447 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.
