www.DataSheet4U.com 19-3482; Rev 0; 10/04 KIT ATION EVALU E L B AVAILA HD/SD Switchable Video Filters and Buffers General Description The MAX7454/MAX7455 triple-channel video reconstruction filters and buffers are ideal for high definition (HD), standard definition progressive scan/noninterlaced (SDp), and standard definition interlaced (SDi) television applications. These devices are a fully integrated solution for filtering and buffering HD and/or SDp/SDi TV signals in component video output format (Y PB PR or RGB). The MAX7454/MAX7455 are compatible with the 1080i, 720p, 480p, and 480i scanning system standards. In addition to having an HD/SD switchable frequency response, the magnitude response can be optimized by approximately 15% by a control input. The input and output signals are DC-coupled to the MAX7454/MAX7455, eliminating the large output AC-coupling capacitors normally used. The MAX7454/MAX7455 output buffers drive a 2VP-P video signal into a standard 150Ω load. The MAX7454 has a gain of +6dB and the MAX7455 has a gain of +12dB. Both devices are available in a 20-pin TSSOP package and are fully specified over the upper commercial (0°C to +85°C) temperature range.
