Title: Bit phase synchronizing circuit
Inventor: NISHI YUMIKO
IPC: H04L7/00
Filed: 1988-03-11
Abstract: PURPOSE:To reduce the effect of dispersion in a gate delay time by using a recovered clock so as to segment a data signal as a recovered data signal and giving proper delay to the recovered data signal and using a system clock so as to apply segmentation again. CONSTITUTION:Since a latch section 10 latches a data signal by a clock with different phase, a detection section 20 detects a changed phase in the data signal from the result. The detection section 20 detects the signal for a prescribed time and stores the change of phase detected so far. A recovery clock selection circuit 30 based on the result of detection selects a clock having a phase offering stable data signal recovery while avoiding the point of time in the change of the data signal among (n)-kind of clocks. A synchronizing section 40 uses the recovered clock to segment the data signal as a recovered data and gives a proper delay to the recovered data so that the data is segmented stably by the system clock and uses the system clock to segment the recovered data while avoiding the changing point of time of the data. Thus, the effect of the dispersion in the gate delay time is reduced.
