TRANSMISSION DEVICE, CAMERA DEVICE, CAMERA CONTROLLER AND CAMERA SYSTEM

摘要

A transmission device includes: a transceiving unit transceiving a serial signal generated by serially converting data based on a clock signal of a frequency selected from frequencies used as clock components of the serial signal and including the clock signal of the selected frequency; a clock recovering unit receiving the serial signal received by the transceiving unit and recovers a recovered clock signal from the serial signal; a match determination unit receiving the recovered clock signal and determines whether a frequency of the recovered clock signal matches each of the frequencies; and a frequency controller performing, if the match determination unit determines that the frequency of the recovered clock signal matches each of the frequencies, a control to determine the frequency of the recovered clock signal as the matching frequency, wherein the frequency of the recovered clock signal is switched between the frequencies until the frequency is determined by the frequency controller.
