MULTIRATE OC-48/24/12/3/GBE/FC SONET/SDH/ATM TRANSCEIVER w/ FEC
[OVERVIEW
The S3067 transceiver implements SONET/SDH and WDM serialization/deserialization, and transmis sion 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 WDM equipment, which consists primarily of the serial transmit inter face and the serial receive interface. The chip handles all the functions of these two elements, in cluding 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.
