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.

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at [email protected] or fax the Reader Response Form in the back of this data sheet to (480) 792-4150. We
welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are using.

EQCO400T8
1.0 DEVICE OVERVIEW
The EQCO400T8 is ideally suited for long-haul IEEE
1394b-2002 connections over Category 5 or Category
6 Ethernet cable at the S400 data rate. It can also be
used at S200 and S100 data rates over even longer
cables, as illustrated in the typical long-haul connection
in Figure 1-1. The EQCO400T8 connects seamlessly
to any IEEE 1394b-2002 compliant physical layer
controller (PHY).
The achievable connection reach with the
EQCO400T8 depends on the input jitter tolerance of
the IEEE 1394 PHY and the quality of the connectors
and cables used. Figure 1-1 shows the typical
performance with CAT5e and CAT6 cables under
nominal conditions.
