PRODUCT BRIEF
S1221
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.
