MAX7481 - (MAX7481 / MAX7482) bidirectional video filters/buffers

Description

The MAX7481/MAX7482 bidirectional video filters/ buffers provide the reconstruction filter and line drive buffer for both composite (CVBS) and S-Video (Y/C) video signals in playback mode, and anti-aliasing in record mode for portable media devices.

Features

  • Composite and S-Video, Video-Playback and VideoRecord Interface for Portable Video Devices.
  • Saves Space by Sharing Connectors in Portable Devices.
  • DirectDrive Eliminates Expensive AC-Coupling Capacitors Blanking Level at Ground with Single Supply.
  • Composite and Y/C Signals.
  • Advanced Power-Down Modes for Extended Battery Life.
  • Low Supply Current in Shutdown Mode, < 1µA (typ).
  • Filter Response Ideal for NTSC and PAL.
  • +6dB (MAX.

www.DataSheet4U.com 19-0671; Rev 0; 11/06 Bidirectional Video Filters/Buffers for Composite and S-Video Portable Media Devices General Description The MAX7481/MAX7482 bidirectional video filters/ buffers provide the reconstruction filter and line drive buffer for both composite (CVBS) and S-Video (Y/C) video signals in playback mode, and anti-aliasing in record mode for portable media devices. Each channel consists of a lowpass filter and an output buffer capable of driving a full 2VP-P video signal into one standard 150Ω load (DC-coupled to ground). In record mode, the MAX7481/MAX7482 output buffers have a gain of +6dB. In playback mode, the MAX7481 output buffers have a gain of +6dB and the MAX7482 output buffers have a gain of +7dB.
