Title:
PARAMETER DETERMINING METHOD AND APPARATUS FOR SPREAD SPECTRUM CIRCUIT, AND CLOCK SPREAD SPECTRUM METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/215206
Kind Code:
A1
Abstract:
A parameter determining method for a spread spectrum circuit, a clock spread spectrum method, a parameter determining apparatus for a spread spectrum circuit, and a clock spread spectrum apparatus. The parameter determining method for a spread spectrum circuit comprises: obtaining a reference time unit and a target frequency (S10); determining a spread spectrum depth coefficient according to the reference time unit and the target frequency (S20); determining whether the spread spectrum depth coefficient is greater than or equal to a reference spread spectrum depth coefficient (S30); under the condition that the spread spectrum depth coefficient is greater than or equal to the reference spread spectrum depth coefficient, determining the spread spectrum depth coefficient as a nominal spread spectrum depth coefficient, and determining a nominal frequency control word according to the nominal spread spectrum depth coefficient (S40); and when the spread spectrum depth coefficient is smaller than the reference spread spectrum depth coefficient, adjusting the reference time unit until the corresponding spread spectrum depth coefficient is greater than or equal to the reference spread spectrum depth coefficient (S50).
