Adaptive clock spreading for platform RFI mitigation

摘要

An apparatus, system, and method, the method including receiving clock frequency parameter information for at least one clock source; receiving radio parameter information for at least one radio receiver; determining one or more spread spectrum clocking (SSC) profiles for the at least one clock source and the at least one radio receiver, each SSC profile to reduce radio frequency interference between the clock and radio receivers; and storing the SSC profiles.

1. A computer-implemented method, the method comprising:
receiving clock frequency parameter information for at least one clock source; receiving radio parameter information for at least one radio receiver; determining, by a processor, one or more spread spectrum clocking (SSC) profiles for the at least one clock source based on the clock frequency parameter information and the at least one radio receiver based on the radio parameter information, each SSC profile to reduce radio frequency interference between the clock and radio receivers, wherein the determining of the one or more SSC profiles for the at least one clock source and the at least one radio receiver comprises:
calculating harmonics of the at least one clock source within a band of one of the at least one radio receiver;calculating, based on the calculated harmonics, a range of clock frequencies having a potential to include harmonic content within the band of one of the at least one radio receiver; anddetermining of the one or more SSC profiles for the at least one clock source and the at least one radio receiver based on the calculated harmonics, the range of clock frequencies having a potential to include harmonic content, and at least one of: a maximum spread limit, a minimum spread limit, and a combination thereof; and storing the SSC profiles.
