Synchronous transfer of streaming data in a distributed antenna system

摘要

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.

1. A method of generating a jitter reduced clock signal from signal transmitted over a communication medium, the method comprising:
receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream; generating a recovered clock signal from the modulated signal that tracks the long-term drift in the modulated signal; and generating a jitter reduced clock signal 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.
