DP83222

CYCLONE^TMTwisted Pair FDDI Stream Cipher Device

General Description

Features

Enables 100 Mbps FDDI signalling over Category

Unshielded Twisted Pair (UTP) cable and Type

Shielded Twisted Pair (STP)

The DP83222 CYCLONE Stream Cipher Scrambler/

Descrambler Device is an integrated circuit designed to in-

terface directly with the serial bit streams of a Twisted Pair

FDDI PMD. The DP83222 is designed to be fully compatible

with the National Semiconductor FDDI Chip Sets, including

the DP83223 TWISTER^TM(Twisted Pair Transceiver). The

DP83222 requires a 125 MHz Transmit Clock and corre-

sponding Receive Clock for synchronous data scrambling

and descrambling. The DP83222 is compliant with the ANSI

X3T9.5 TP-PMD draft standard and is required for the re-

duction of EMI emission over unshielded media. The

DP83222 is specified to work in conjunction with existing

twisted pair transceiver signalling schemes such as MLT-3

or NRZI and enables high bandwidth transmission over

Twisted Pair copper media.

Reduces EMI emissions over Twisted Pair media

Compatible with ANSI X3T9.5 TP-PMD Standard

Requires a single 5V supply

Transparent mode of operation

Flexible NRZ and NRZI format options

Advanced BiCMOS process

Signal Detect and Clock Detect inputs provided for en-

hanced functionality

Suitable for Fiber Optic PMD replacement applications
