Advance Information

This document contains information on a product under development. The parametric information

contains target parameters that are subject to change.

CN8331/CN8332/CN8333

Single/Dual/Triple E3/DS3/STS-1 Line Interface Unit

Distinguishing Features

The CN8333 is a three-channel, E3/DS3/STS-1 fully-integrated Line Interface Unit (LIU).

It is configured via external pins and does not need a microprocessor interface.

Each channel has an independent equalizer on the receive side requiring no user

configuration. Also, each channel has a programmable transmit pulse shaper that can

be set to ensure that the cross-connect pulse mask requirement is met for transmit

cable length up to 450 feet. The CN8332 is a dual-channel, and the CN8331 is a

single-channel LIU with performance identical to the CN8333.

The CN8333 gives the user new economies of scale in concentrator applications

where three DS3 or STS-1 channels are concentrated into a single STS-3 channel. By

including three independent transceivers on a chip, significant external components are

eliminated, with the exception of 1:1 coupling transformers, termination resistors, and

supply bypass capacitors.

•

Can be used as a data transceiver

over a maximum of 900 feet of Type

734/728 coaxial cable or equivalent

in an on-premise environment

•

Programmable pulse filtering to meet

cross-connect pulse masks (ANSI

T1.102-1993)

Meets jitter specifications of Bellcore

GR499 and GR253

•

Large input dynamic range

Alarms for coding violation and loss

of signal

•

Full diagnostic loopback capability

Uses a minimum of external

components

NOTE: In this document "x" is used to represent the number of channels:

x = 1 (CN8331), x = 2 (CN8332), and x = 3 (CN8333).

•

Compatible with ITU-T G.703, G.823

Independent power down mode per

channel
