Spread spectrum clocking settings adjusting method and wireless packet receiving method

Abstract

A spread spectrum clocking (SSC) settings adjusting method includes: expanding candidate SSC settings for a system scenario; applying the candidate SSC settings to an integrated circuit (IC) device that stores a predefined look-up table; measuring candidate signal-to-noise ratios (SNRs) of the IC device respectively under the SSC clocking settings; selecting a selected SSC setting that has a highest SNR of the candidate SNRs from the candidate SSC settings corresponding to the system scenario; and substituting an SSC setting of the predefined look-up table corresponding to the system scenario with the selected SSC setting, so as to update the predefined look-up table stored in the IC device.
