S3157
GPON Transceiver With CDR
Description
The S3157 GPON transceiver chip is a
fully integrated serialization/
deserialization GPON OC-48/24/12
transceiver interface device. The S3157
receives an OC-48/24/12 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 GPON transmission
standards. The device is suitable for
GPON-based 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 S3157 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.

Empowering Intelligent Optical Networks
The low jitter LVPECL interface is
compliant with the bit-error rate
requirements of the ITU-T standards.
The S3157 is packaged in a 196 PBGA,
offering designers a small package
outline.
Overview
The S3157 transceiver implements
GPON serialization/deserialization, and
transmission functions. This chip can be
used to implement the front end of
GPON 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
S3157 is divided into a transmitter
section 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
2. Serial-to-parallel conversion
3. 16-bit parallel output
Due to the asynchronous nature of the
GPON, the FPGA that connects to the
S3157 has to accommodate for the 1/2
upstream data rate.
