100Base-FX Integrated PHYceiverTM
General Description
Features
The ICS1889 is a fully integrated physical layer device
supporting 100 Megabits per second CSMA/CD Fast
Ethernet fiber optic applications. It is designed to support
the requirements of DTEs (adapter cards), repeaters and
switches. It is compliant with the ISO/IEC 8802 Fast
Ethernet standard for 100Base-FX. It provides a Media
Independent Interface (MII) allowing direct chip-to-chip
connection, motherboard-to-daughter board connection or
connection via a cable in a similar manner to the AUI
approach used with 10Base-Tsystems. A station
management interface is provided to receive command
information and send status information. It transmits and
receives NRZI data and interfaces directly to the optical
transceiver. It can operate in either half duplex or full
duplex.
