Abstract

The disclosure is related to a serializer and a deserializer. The serializer includes a serializing module and a data up-conversion processing module. The data up-conversion processing module receives a data packet sequence from a media access control block based on an output operating frequency and outputs the data packet sequence based on a serial operating frequency. The deserializer includes a deserializing module and a plurality of data down-conversion processing modules. The deserializer generates a data operating frequency based on a deserial operating frequency and outputs a restored data packet sequence based on the data operating frequency. The disclosure transmits or receives data in accordance with the operating frequency of the media access control block, and the data is exchanged at a transmission frequency that meets the transmission specification requirements of the physical layer. Thus, the convenience of using a serializer and a deserializer is improved.
