摘要：PURPOSE:To ensure the phase synchronism of a sampling pulse by using plural clock line signals in a device receiving a character multiplex signal, derecting the phase locked state for plural number of times and phase locking the signal to character information. CONSTITUTION:An oscillating signal is applied to a freuency dividing circuit 23 which frequency-divides the oscillating signal and produces a sample pulse for a signal to be sampled, while inverting the phase at each period of a transmission rate of the signal to be sampled. Thus, the sampling pulse of a frequency division circuit 23 is shifted sequentially in the phase lag or lead for each half period of the oscillating signal at each period of the transmission rate so as to obtain the sampling pulse SP phase-locked to the signal to be sampled at the frequency division circuit 23.
