DP83231 CRDTM Device
(FDDI Clock Recovery Device)
General Description
The DP83231 CRD device is a clock recovery device that
has been designed for use in 100 Mbps FDDI (Fiber Distrib-
uted Data Interface) networks The device receives serial
data from a Fiber Optic Receiver in differential ECL NRZI
4B 5B group code format and outputs resynchronized NRZI
received data and a 125 MHz received clock in differential
ECL format for use by the DP83251 55 PLAYERTM device
Features
