CLOCK CORRECTION METHOD AND CIRCUIT UTILIZING TRAINING SEQUENCE TO CORRECT OSCILLATOR OUTPUT, AND REFERENCE CLOCK GENERATION METHOD AND CIRCUIT UTILIZING TRAINING SEQUENCE TO GENERATE REFERENCE CLOCK

摘要

A clock correction method is provided. The clock correction method includes the following steps: receiving an equalization training sequence specified by a communication protocol, wherein the equalization training sequence includes a specific pattern occurring repeatedly; performing frequency division on the equalization training sequence according to a number of toggles of the specific pattern so as to generate an equalization training sequence clock; and correcting a frequency of an output clock of an oscillator according to the equalization training sequence clock.
