A bit synchronizer for producing a clock signal and synchronizing the clock signal to a digital data stream. The digital data stream is used to generate first and second bit rate clocks, each of which have a clock cycle time equal to one bit time. The first bit rate clock is input to a phase lock-looped...http://www.google.com/patents/US4780893?utm_source=gb-gplus-sharePatent US4780893 - Bit synchronizer
