An object of the present disclosure is to provide a transmission device, a reception device, and a transmission-reception system capable of achieving downsizing and communication at a high frame rate. A transmission device includes a control signal reception unit that receives a control signal input from an external device and including predetermined information, and a control unit that controls switching between first communication and second communication on a basis of switching information, the switching information being included in the predetermined information as necessary, the switching information indicating switching between the first communication in which host communication is executed in a blanking period among one frame period and the second communication in which host communication is executed in a blanking period and a data output period among one frame period.

Transmission device, reception device, and transmission-reception system

Provided is a transmission/reception system that can implement miniaturization and a reduced number of wires for transmitting a signal between a sensor device and a reception device. The sensor device includes a data transmitting unit configured to transmit imaging data synchronized with a first clock signal to the reception device through a first signal transmission path, a clock signal transmitting unit configured to transmit a second clock signal with a lower frequency than the first clock signal to the reception device through a second signal transmission path, and a control signal communicating unit configured to communicate a control signal necessary for control of the first clock signal with the reception device through the second signal transmission path. The reception device includes a signal generating unit configured to generate the control signal on the basis of a comparison result of a comparison between a reference clock signal and any one of the second clock signal based on the first clock signal and the second clock signal transmitted from the sensor device through the second signal transmission path, and a control signal communicating unit configured to communicate the control signal with the sensor device through the second signal transmission path.

Sensor device, reception device, and transmission/reception system

A communication system according to the present disclosure includes a transmission device and a reception device. The transmission device includes a phase synchronizer, a generator, and a controller. The phase synchronizer generates a first clock signal, and is configured to be able to change a frequency of the first clock signal. The generator generates a transmission signal on the basis of the first clock signal. The controller controls the generator and the phase synchronizer to change the frequency of the first clock signal while generating the transmission signal. The reception device receives the transmission signal.
