SERIAL COMMUNICATION CONTROL CIRCUIT

摘要

In a serial communication control circuit, serial data transmitted from a transmission processing unit is switched to data generated in a mark ratio improvement data generation unit depending on a switch signal from the transmission processing unit, and is transmitted. Thereby, mark ratio improvement data is inserted in a transmission signal to improve a mark ratio during communication, thereby preventing reception signal's jitters from increasing.

主权项

1. A serial communication control circuit for transmitting and receiving encoded data, comprising:
a transmission processing unit for generating serial data to be transmitted; a mark ratio improvement data generation unit for generating mark ratio improvement data in addition to the generated transmission data; and a transmission data switch unit for transmitting serial data transmitted from the transmission processing unit and switching the serial data to data generated in the mark ratio improvement data generation unit when a switch signal is output from the transmission processing unit.
