PRODUCT BRIEF
S3485
Description
The S3485 SONET/SDH transceiver chip is a fully
integrated serialization/deserialization SONET
multi-rate interface device. The S3485 receives a
scrambled Non-Return-to-Zero (NRZ) signal and
recovers the clock from the data. The chip
performs all necessary serial-to-parallel and
parallel-to-serial functions in conformance with
the SONET/ SDH/ Gigabit Ethernet/ Fibre
Channel/ HDTV/ ESCON/ DTV/ D1 transmission
standards. The device is suitable for SONET-
based WDM applications. The diagram in Figure
1 shows a typical network application.
On-chip clock synthesis is performed by the
high-frequency Phase-Lock Loop (PLL) on the
S3485 transceiver chip, allowing the use of a
slower external transmit clock reference. The
chip can be used with a divide by 16 reference
clock in support of existing system clocking
schemes.
The low-jitter parallel LVDS interface is
compliant with the bit-error rate requirements
of the Telecordia and ITU-T standards. The
S3485 is packaged in a 121 PBGA offering
designers a small package outline.
Overview
The S3485 transceiver implements SONET/
SDH/ Gigabit Ethernet/ Fibre Channel/ HDTV/
ESCON/ DTV/ D1 serialization/deserialization
and transmission functions. This chip can be
used to implement the front end of SONET/
SDH/ Gigabit Ethernet/ Fibre Channel/ HDTV/
ESCON/ DTV/ D1 equipment, which consists
primarily of the serial transmit interface and the
serial receive interface. The chip handles all the
functions of these two elements, including
parallel-to-serial and serial-to-parallel
conversion, clock generation, and system
timing. The system timing circuitry consists of
data stream management and clock
distribution throughout the front end. Of the
listed bit rates, only the associated SONET/SDH,
Fibre Channel and Gigabit Ethernet protocols
have been validated to their respective
standards. AMCC has characterized the
remaining bit rates with a PRBS 2
31
pattern but
has not validated their associated protocols
against any known standard. It is the
responsibility of the end user to evaluate and
verify protocol/standards compliance for all
other bits rates that are intend for use.
