S3033 OVERVIEW
The S3033 transceiver implements SONET/SDH se-
rialization/deserialization, transmission, and frame
detection/recovery functions. The block diagram in
Figure 4 shows the 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 handles all the functions of these two
elements, including parallel-to-serial and serial-to-par-
allel conversion, clock generation, and system
timing. The system timing circuitry consists of man-
agement of the data stream, framing, and clock
distribution throughout the front end.
The S3033 is divided into a transmitter section and a
receiver section. The sequence of operations is as
follows:
Transmitter Operations:
Receiver Operations:
Internal clocking and control functions are transpar-
ent to the user. Details of data timing can be seen in
Figures 7 through 10.
