HD/SD Switchable Video Filter and Buffer 6dB 5V 20-Pin TSSOP EP

The MAX7454 triple-channel video reconstruction filters and buffers are ideal for high definition (HD), standard definition progressive scan/non interlaced (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 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 eliminating the large output AC-coupling capacitors normally used. The MAX7454 output buffers drive a 2VP-P video signal into a standard 150? load. The MAX7454 has a gain of +6dB. 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.
