Abstract

PURPOSE:To enable exact adjustment and setting of clock operations by compensating the error between the oscillating frequency and standard frequency of the reference oscillator, instead of performing minute adjustments under measures such as trimmer adjustment, etc., on the oscillating frequency of the reference oscillator.
