Timing signal supplying device of doubled timing synchronous system

摘要

A timing signal supplying device in a doubled timing synchronous system includes: a timing signal adjusting portion which feeds back a timing signal of a timing signal receiving circuit and a frequency signal of a transmitting buffer to regenerate a timing signal and compares the timing signal with an external input timing signal to detect and correct an error of the timing signal; and a timing signal transmitting portion which sequentially transmits the corrected signal of the timing signal adjusting portion and the regenerated timing signal to the timing signal receiving circuit.
