Publication number: 20250112627Abstract: In a system on a chip (SoC), clock selection circuitry provides a selected one of a first or second clock signal as an output clock based on at least one of a first flag and a second flag. This output clock is provided as a reference clock to one or more phase locked loops (PLLs) of the SoC. The SoC includes a first clock path which receives a first oscillating signal from a first clock source external to the SoC to generate the first clock signal, and a second clock path which receives a second oscillating signal from a second clock source external to the SoC to generate the second clock signal. A first glitch monitor asserts the first flag when a glitch is detected in the first oscillating signal, and a second glitch monitor configured asserts the second flag when a glitch is detected in the second oscillating signal.Type: ApplicationFiled: September 20, 2024Publication date: April 3, 2025Inventors: Nihaar N. Mahatme, Srikanth Jagannathan, Akhilesh Kumar Singh, Girraj Kumar Agrawal
