Integrated Reference Clock PLL

The processor includes a phase lock loop (PLL) that generates the reference clock for the processor from a fixed crystal clock. The processor reference clock is also referred to as Base Clock or BCLK.

By integrating the BCLK PLL into the processor die, a cleaner clock is achieved at a lower power compared to the legacy PCH BCLK PLL solution.

The BCLK PLL has controls for RFI/EMI mitigations as well as Overclocking capabilities.
