Hd/sd Switchable Video Filters And Buffers

The MAX7454 MAX7455 triple-channel Video recon- struction Filters and Buffers are ideal for high definition (HD), standard definition progressive scan/noninter- laced (SDp), and standard definition interlaced (SDi) Television applications. These devices are a fully inte- grated 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 compati- ble 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-cou- pling capacitors normally used. The MAX7454 MAX7455 output Buffers drive a 2VP-P Video signal into a standard 150 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 (0C to +85C) temperature range. By Maxim Integrated Products
