Title:
DATA TRANSMISSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/269954
Kind Code:
A1
Abstract:
The present invention suppresses power supply noise while reducing power consumption or current consumption in a data transmission circuit. The data transmission circuit includes first and second drive circuits and an operating state control circuit. The first drive circuit drives first data that causes the transition to occur or not in synchronization with a clock signal. The second drive circuit drives second data that transitions at timings at which the first data does not transition in synchronization with the clock signal. The operating state control circuit individually controls the operating states of the first and second drive circuits.
