HD/SD Switchable Video Filters and Buffers
General Description
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 P
B
P
R
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 2V
P-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.
