A 1.0625-Gbit /s Fibre Channel Chipset with Laser Driver

This chipset implements the Fibre Channel FC-0 physical layer specification at 1.0625 Gbits/s. The transmitter features 20:1 data multiplexing with a comma character generator and a clock synthesis phase-locked loop, and includes a laser driver and a fault monitor for safety. The receiver provides the functions of clock recovery, 1:20 data demultiplexing, comma character detection, and word alignment, and includes redundant loss-of-signal alarms for eye safety. A single-chip version with both transmitter and receiver integrated is designed for disk drive applications using the Fibre Channel arbitrated loop protocol.
