ABSTRACT:
Synchronization with a signal derived from code violations in periodic data block preambles, and derived using analog circuits provides for a very low jitter clock. The method involves detecting the amplitude of an analog signal derived from the preamble. The amplitude exceeds a preset value whenever a code violation occur is detected. The frequency of the preamble may be a fraction or a multiple of the synchronized clock.
