Method and apparatus for data and clock recovery in a biphase-coded data signal

摘要

A method and apparatus for data and clock recovery in a biphase-coded data signal is described, in which the data signal is sampled using a sampling frequency that is greater than twice the bit frequency of the data signal. The bit limits of the data signal are then determined from the sampling values and used to recover the both the data bits and the corresponding bit clock pulse of the data signal.
