1. A communication system, comprising:
- a first unit configured to clock an encoded data stream onto a data interface using a modulated signal; and
at least one second unit configured to receive the modulated signal and encoded data stream from the first unit, the at least one second unit including;
a circuit configured to generate a jitter reduced clock signal by removing jitter from a recovered clock signal while allowing the jitter reduced clock signal to track long-term drift in the modulated signal, wherein the at least one second unit is configured to generate the recovered clock signal from the modulated signal.

Abstract
Method and apparatus for generating a jitter reduced clock signal from signal transmitted over a communication medium includes receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream. A recovered clock signal is generated from the modulated signal and tracks the long-term drift in the modulated signal. A jitter reduced clock signal is generated by filtering the recovered clock signal with a filtering circuit having a bandwidth sufficient to remove jitter while allowing the jitter reduced clock signal to track the drift in the modulated signal.
