The invention discloses a high-speed
asynchronous serial communication method. The method comprises the following
processing steps of: inputting a high-speed serial
signal, performing over-sampling on the input serial
signal, sending the sampled data to a data determination
recovery module, detecting whether
data redundancy or missing exists in the currently input sampled data through the data determination
recovery module according to a
phase relationship between former output data and clocks, performing operation of redundant data removal, missed
data recovery or normal data determination, updating a
phase relationship between current output data and clocks, inputting the determined valid data to a data alignment and series-parallel conversion operation module for performing the data frame format alignment operation according to a data communication protocol, and outputting the valid data. Circuit modules related to the method comprise a data sampling module, the data determination
recovery module and the data alignment and series parallel conversion operation module. The method belongs to the field of communication; and through adoption of the method, the data sampling error rate caused by
clock or
signal jittering in a high-speed serial transmission communication
system is reduced, the implementation method is simple and the
system is reliable.
