Circuit device having two communication interfaces for faster and slower transmission speeds, and transmission module, electronic apparatus, and moving object that have the circuit device

摘要

To provide different paths for communication of a serial signal required for high-speed communication and communication of transmission data that may be handled in low-speed communication, a circuit device includes a serial interface that receives a serial signal transmitted from a controller at a first communication speed, a transmission data input terminal that receives transmission data transmitted from the controller at a second communication speed slower than the first communication speed, and a transmission circuit that outputs a transmission signal corresponding to the transmission data based on the serial signal and the transmission data.
