• Manufacturer Part Number: S3057
• Description: Bicmos Lvpecl Clock Generator Sonet/sdh/atm Oc-12 Transmitter And Receiver Multirate (oc-48/24/12/3/gbe) Sonet/sdh/atm Transceiver
• Manufacturer: AMCC (Applied Micro Circuits Corp)

S3063 OVERVIEW
The S3063 transmitter implements SONET/SDH se-
rialization and transmission functions. The block dia-
gram 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
interface. The chip includes parallel-to-serial conver-
sion and system timing. The system timing circuitry
consists of a high-speed phase detector, clock di-
vider, and clock distribution throughout the front end.
