DIGITAL PHASE DETECTOR FOR BIT SYNC.

摘要

The transition of clock-pulse which is retiming the inputted NRZ data generates in unit interval of data bit. The transition of clock- pulse is not automatically adjusted and depends on the accuracy and temperature character of device. And, self-tuning retiming circuits have shortcomings of the limitation of bit-speed and of the gitters. By comparing the phase of retiming clock-pulse and unit interval of inputted data bits, compared results are given digitally for the phase detector which outputs phase information easily matching digital circuits.
