Method for clock recovery of a digital signal on the reception side

摘要

The method involves using the degree of filling of a FIFO memory into which the digital signals are written. At the start of transmission the several cells of the received signal are written into the FIFO memory with the received clock signal, until the memory is half full. The digital signal in the memory is read out using a read out clock with a repetition frequency lower than that of the received clock. During read out a signal for controlling the frequency of the read out clock is derived from the current state of the FIFO memory.
