Abstract
A transceiver providing Fiber Channel data transfer speeds may be implemented in a lower performance process technology as a single unit, thereby reducing cost. A serializer and deserializer each having multiple lower frequency clocks are provided to obtain the equivalent of a high speed clock capable of use in Fiber Channel systems. Lower speed parallel data is converted to higher speed serial data, and vice versa. A digital frequency counter along with a phase detection circuit provides synchronization. Comma detection is provided for data word alignment.
