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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
The differential gain and differential phase specifications apply to standard-definition composite video signals only.
Note 2:
This applies for an anti-aliasing filtering application using a 0.1µF input capacitor. This does not apply for a video recon-
struction application, since there is no input-coupling capacitor.
