Advance Information
This document contains information on a product under development. The parametric information
contains target parameters that are subject to change.
CX28331/CX28332/CX28333
Single/Dual/Triple E3/DS3/STS-1 Line Interface Unit
The CX28333 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 CX28332 is a dual-channel, and the CX28331 is a
single-channel LIU with performance identical to the CX28333.
The CX28333 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.
NOTE: In this document, "i" is used to represent the number of channels:
i = 1 (CX28331), i = 2 (CX28332), and i = 3 (CX28333).
