Abstract
A phase synchronizing circuit for a time axis shift correcting circuit includes a closed-loop phase lock circuit of a phase comparator, a VCO, and a frequency division counter, for providing an output signal phase locked to a reference signal included in an input data signal. Hold circuitry, responsive to a hold instruction signal, is provided to hold the phase relationship of the output signal held just prior to the hold instruction signal for the duration of the hold instruction signal. The hold instruction signal is produced in response to a predetermined condition of the input data signal.
