MAX7481, MAX7482 Bidirectional Video Filters/Buffers For Composite And S-Video Portable Media Devices

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 150 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.
The MAX7481 MAX7482 feature DirectDrive" by utilizing an internal negative Charge Pump and Regulator to maintain the output blanking level at ground, eliminating the need for a negative supply voltage, a large output coupling capacitor, or a sag correction configuration.
The MAX7481 MAX7482 operate from a single +2.7V to +3.6V power supply. These devices are available in a space-saving 28-pin TQFN package and operate over the -40C to +85C e 543 xtended temperature range.
