SONET/SDH/ATM OC-48 16 BIT TRANSCEIVER WITH CDR
May 25, 2001 / Revision A
S3055 OVERVIEW
The S3055 transceiver implements SONET/SDH seri-
alization/deserialization, and transmission 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 serial
receive interface. The chip handles all the functions of
these two elements, including parallel-to-serial and
serial-to-parallel conversion, clock generation, and
system timing. The system timing circuitry consists of
management of the data stream and clock distribution
throughout the front end. Table 1 shows the sug-
gested interface devices for the S3055.
The S3055 is divided into a transmitter section and a
receiver section. The sequence of operations is as
follows:
Transmitter Operations:
1. 16-bit parallel input
2. Parallel-to-serial conversion
3. Serial output
Receiver Operations:
1. Clock and data recovery from serial input
2. Serial-to-parallel conversion
3. 16-bit parallel output
Internal clocking and control functions are transpar-
ent to the user.
