APPARATUS FOR DETECTING REAL TIME CLOCK FREQUENCY OFFSET AND METHOD THEREOF |
摘要 |
An apparatus for detecting a real time clock frequency offset includes: an overlap detecting unit detecting an overlap signal having overlap information of a predetermined reference clock and a predetermined real time clock; an envelope signal creating unit creating an envelope signal having envelope information of the overlap signal; and a frequency counter unit calculating a frequency of the envelope signal that is a frequency offset of the real time clock, by using a first clock number created by counting the reference clock for one period of the envelope signal and a frequency of the reference clock.
