E-mail at docerrors@microchip.com. 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., DS30000000A is version A of document DS30000000).
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.

EQCO875SC.3/EQCO850SC.3
1.0 DEVICE OVERVIEW
The EQCO875SC.3 single-coax transceiver is
designed to simultaneously transmit and receive
signals on a single 75 coax cable for Fast Ethernet. A
sister product, the EQCO850SC.3, can achieve similar
performance when used in 50 coaxial systems.
The EQCO875SC.3 is ideally suited for Fast Ethernet
connections over a 75 coax cable at a 125 Mbps data
rate. The EQCO875SC.3 connects seamlessly to any FX-
compliant physical layer controller (PHY). For correct
operation, the signals are expected to be 4B/5B encoded,
DC balanced and to have a bit rate of 125 Mbps.
This EQCO875SC.3 is useful and economical for
connecting remote PoE-enabled Fast Ethernet IP
cameras and other Ethernet over Coax applications.
