Clock, data and time recovery using bit-resolved timing registers |
摘要 |
A clock recovery method is disclosed wherein the FIFO delay of data words and the phase difference between a data word and a receiver clock are used to time data transmissions from a transmitter. The phase difference between the data word and the receiver clock is determined by the offset of a word relative to a desired position in a storage buffer. The FIFO delay is determined either by measuring the difference between a read pointer and a write pointer in the FIFO or, alternatively, by calculating the difference between a timestamp of the time a data word entered the FIFO and the current time as the data word is read from the FIFO.
