Abstract :
This paper describes a 0.8 μm CMOS communication system designed for 622 Mb/s SDH/SONET links. The single-chip system implements all line interface functions needed by the link. The emitter performs parallel bus interface, parallel-to-serial conversion and optional scrambling for line testing. An output buffer to attack the laser driver is also included. The receiver performs post-amplification, clock recovery, frame detection and optional descrambling, followed by serial-to-parallel conversion and parallel bus interface
