CXB1441R

Cable Equalizer with 2-system Switching Function

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)
