Claims

[Claims for Utility Model Registration] 1. An oscillator that generates a clock pulse that has an arbitrary phase relationship with a synchronization signal and has a stable period, a conversion means that converts the clock pulse into a monotonically increasing pulse wave, and converts the pulse wave. an n-bit latch that latches the output of the A/D converter, and inputs the output of the data stored in the latch through the D/A converter and the monotonically increasing pulse wave to generate a sampling pulse. A phase-locked circuit equipped with a comparator that outputs. 2. The phase synchronized circuit according to claim 1, wherein the data stored in the latch is sent to the D/A converter through an adder that adds correction data. 3. The phase synchronized circuit according to claims 1 and 2, wherein the converting means is an integrating circuit that converts the clock pulse into a sawtooth wave.
