Feature.
A kind of Serdes speed matching methods are provided in the present embodiment, and Fig. 1 is according to the ... of the embodiment of the present invention
The flow chart of Serdes speed matching methods, as shown in Figure 1, this method comprises the following steps：
Step S102 is configured the first stringization/rate of unstringing for Serdes, and is gone here and there with first stringization/rate of unstringing
Change/unstrings；
Whether step S104 judges the corresponding synchronization parameter of string of the output data with configuration/rate of unstringing of Serdes
Matching；
Step S106 determines the input of stringization/rate of unstringing and Serdes of configuration in the case where the judgment result is yes
Rate is identical.
The present embodiment through the above steps, by the output data of Serdes with configuration stringization/unstring corresponding to rate
Synchronization parameter is matched, due to only in the input rate of Serdes it is identical with the string of configuration/rate of unstringing,
The output data of Serdes could be same with the normal the output phase of stringization/rate of unstringing of above-mentioned configuration, in this case,
The output data of Serdes synchronization parameter corresponding with the string of configuration/rate of unstringing can match.Therefore, when Serdes's
In the case of stringization/synchronization parameter for unstringing corresponding to rate of output data and configuration is matched, then illustrate the input of Serdes
