AMCC (Applied Micro Circuits Corporation ) : S3019

SONET/SDH/ATM OC-3/12 Transceiver w/CDR

The S3019 SONET/SDH transceiver chip is a fully integrated serialization/deserialization SONET OC-12 (622.08 Mbit/s) and OC-3 (155.52 Mbit/s) interface de-vice. The chip performs all necessary serial-to-parallel and parallel-to-serial functions in conformance with SONET/SDH transmission standards. The device is suitable for SONET-based ATM applications. Figure 1 shows a typical network application. On-chip clock synthesis is performed by the high-frequency phase-locked loop on the S3019 transceiver chip allowing the use of a slower external transmit clock reference. Clock recovery is performed on the device by synchronizing its on-chip VCO directly to the incoming data stream. The S3019 also per-forms SONET/SDH frame detection. The chip can be used with a 19.44, 38.88, 51.84 or 77.76 MHz refer-ence clocks, in support of existing system clocking schemes.
