DATA TRANSMISSION SYSTEM PROVIDED WITH MULTIPLEXED LVDS INTERFACE

摘要

PROBLEM TO BE SOLVED: To reduce the number of physical signal lines on an interface by converting a signal whose frequency is 20MHz by using an element utilizing LVDS technology to transmit the signals in the interface between image processors or the like.;SOLUTION: An LVDS transmitter part 12 in a data transmitter 10 multiplexes and converts signals such as a reference clock signal, a synchronizing signal and a data signal from an interface control part 11 by LVDS transfer clocks generated from an LVDS transfer clock generation part 13 into LVDS signals of which the number of signal lines is reduced and transfers the LVDS signals, and converts the LVDS transfer clocks as a group of LVDS signals and transfers the LVDS signal group. An LVDS receiver part 21 in a data receiver 20 demodulates the multiplexed LVDS signals sent from the LVDS transmitter part 12 by using the LVDS transfer exclusive clocks sent from the LVDS transmitter part 12 and sends the demodulated LVDS signals to an interface control part 22.;COPYRIGHT: (C)2004,JPO
