Description

The S1221 SONET/SDH transceiver is one of the

latest additions to the AMCC product family.

The S1221 device provides fully integrated

serialization/de-serialization capabilities with

four independent transceivers. The device

performs all necessary parallel-to-serial and

serial-to-parallel functions in conformance with

the SONET/SDH transmission standards.

Clock and Data Recovery are provided for the

standard operating rates of 155.52 Mbps (OC-3)

and 622.08 Mbps (OC-12).

The S1221 can also be provisioned to a mix and

match OC-3 and OC-12 data streams within the

same device.

The S1221 can be configured in MII (Media

Independent Interface) mode (MII Mode) or in a

Non-MII mode.

The figure below, System Block Diagram, shows

a typical network application.

Overview

The S1221 can be used to implement the front

end of SONET/SDH equipment which consists

primarily of the serial transmit interface and the

serial receive interface. The Low Voltage LVDS or

LVPECL interfaces guarantee compliance with

the bit-error rate requirements of the Telcordia

and ITU-T standards.

The S1221 is divided into four Transceiver

modules with each possessing a clock recovery

unit. Each of the modules can run at OC-3 or

OC-12 data rates, independent of the other

modules.

The S1221 performs SONET/SDH frame

detection.

The S1221 is divided into four transmitter

channels and four receiver channels.

The sequence of operations is as follows for

each Channel:

Transmitter Operations

• 8-bit parallel data input

• Parallel-to-serial conversion

• Serial data output

Receiver Operations For One Channel

• Serial data input

•Clock and Data recovery

• Serial-to-parallel data conversion

• 8-bit parallel data and clock output

Internal clocking and control functions are

transparent to the user.
