S3083 OVERVIEW
The S3083 transmitter implements SONET/SDH se-
rialization and transmission functions. The block dia-
gram in Figure 4 shows basic operation of the chip.
This chip can be used to implement the front end of
SONET equipment, which consists primarily of the
serial transmit interface and the serial receive inter-
face. The chip includes parallel-to-serial conversion
and system timing. The system timing circuitry con-
sists of a high-speed phase detector, clock dividers,
and clock distribution throughout the front end.
