S3155
SONET/SDH/ATM OC-48 Transceiver With CDR
Empowering Intelligent Optical Networks 1
PB1135_v1.01_05/09/03
Description
The S3155 SONET/SDH transceiver
chip is a fully integrated serialization/
deserialization SONET OC-48 (2.488 -
2.67 Gbps) interface device. The S3155
receives an OC-48 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 SONET/SDH
transmission standards. The device is
suitable for SONET-based WDM
applications. The figure below shows a
typical network application.
On-chip clock synthesis is performed by
the high-frequency Phase-Locked Loop
(PLL) on the S3155 transceiver chip
allowing the use of a slower external
transmit clock reference. The chip can
be used with a 155.52 or 166.63 MHz
reference clock in support of existing
system clocking schemes.
The low jitter LVPECL interface is
compliant with the bit-error rate
requirements of the Telecodia and ITU-T
standards. The S3155 is packaged in a
196 PBGA, offering designers a small
package outline.
Overview
The S3155 transceiver implements
SONET/SDH serialization/deserializa-
tion, and transmission functions. This
chipcanbeusedtoimplementthefront
end of SONET equipment, which con-
sists primarily of the serial transmit inter-
face 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
S3155 is divided into a transmitter sec-
tion and a receiver section. The
sequence of operations is as follows:
Transmitter Operations:
1. 16-bit parallel input
2. Parallel-to-serial conversion
3. Serial output
Receiver Operations:
1. Clock and data recovery from serial
input
2. Serial-to-parallel conversion
3. 16-bit parallel output
