Data transmission/reception system

摘要

In the process of transferring a clock signal and a plurality of data signals which are in synchronization with the clock signal, a driving pulse width of a driver switch is feedback-controlled by a clock transmission system ( 12 ), whereby the clock signal is transmitted at a small amplitude. A control signal having the pulse width is used for controlling the driver switch in each data transmission system ( 13 ), whereby transfer of each data signal at a small amplitude is realized at the same time. Further, in a clock reception system ( 10 ), the control signal having the pulse width is used in delay control of a clock delay circuit, whereby an optimum latch timing of received data in each data reception system ( 11 ) is realized.
