General Description
The EQCO400T8 is a multi-rate adaptive cable equal-
izer designed to restore signals received over Cat 5 or
Cat 6 Unshielded Twisted Pair (UTP) cable. For correct
operation, the signals must be NRZ (Non-Return-to-
Zero) encoded, DC-balanced with a maximum run
length of 10 bits and have a speed (edge rate) of
between 100 Mbps and 500 Mbps.
