Based on the foregoing, it will be appreciated that technologies for adaptive spread-spectrum clocking to limit interference in a target band are presented herein。 While embodiments are described herein in regard to an HDD device, it will be appreciated that the embodiments described in this disclosure may be utilized in any electronic device that contains a clock signal generator that radiates EMI, including storage devices, computing devices, communication devices, networking devices, and the like。

Further, while the embodiments described herein refer to reduction of interference of a 320 MHz clock signal in wireless communication bands, it will further appreciated that the embodiments described in the disclosure may be utilized to produce adaptive SSC profiles 404 with reduced radiation in any target band or bands based on any clock frequency and/or harmonics thereof。spread spectrum clocking The above-described embodiments are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the present disclosure。

The logical steps, functions or operations described herein as part of a routine, method or process may be implemented (1) as a sequence of processor-implemented acts, software modules or portions of code running on a controller or computing system and/or (2) as interconnected machine logic circuits or circuit modules within the controller or electronic device. The implementation is a matter of choice dependent on the performance and other requirements of the system. Alternate implementations are included in which steps, operations or functions may not be included or executed at all, may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present disclosure.
