S3042 OVERVIEW
The S3042 receiver implements SONET/SDH
deserialization and frame detection functions. The
block diagram in Figure 2 shows basic operation of
the chip. This chip can be used to implement the
front end of SONET equipment, which consists pri-
marily of the serial transmit interface and the serial
receive interface. The chip includes serial-to-parallel
conversion and system timing. The system timing
circuitry consists of management of the datastream,
framing, and clock distribution throughout the front end.
