DP83241 CDD

TM Device

(FDDI Clock Distribution Device)

General Description

The CDD device is a clock generation and distribution de-

vice intended for use in FDDI (Fiber Distributed Data Inter-

face) networks The device provides the complete set of

clocks required to convert byte wide data to serial format for

fiber medium transmission and to move byte wide data be-

tween the PLAYERTM and BMACTM devices in various sta-

tion configurations 125 MHz and 125 MHz differential ECL

clocks are generated for the conversion of data to serial

format and 125 MHz and 25 MHz TTL clocks are generated

for the byte wide data transfers
