• Manufacturer: AMCC (Applied Micro Circuits Corp)

S3044 OVERVIEW
The S3044 receiver implements SONET/SDH
deserialization and frame detection functions. The
block diagram in Figure 2 shows the basic opera-
tion 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 se-
rial
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.
