Cable Equalizer with 2-system Switching Function
CXB1441R
Description
The CXB1441R is a cable equalizer that compensates the attenuation resulting from cable transfer of small-
amplitude differential NRZ signals.
This chip has two sets of input ports comprising three pairs of differential data signals and one pair of
differential clock signals. It equalizes and quantizes the signals from the optional ports and then outputs the
signal from the output ports. NRZ signals from 250Mb/s to 1.65Gb/s are supported.
(Applications: High-speed digital video signal switching and compensation of cable attenuation)
Features
Two sets of input ports comprising three pairs of differential data signals and one pair of differential clock signals
