摘要
Low power, jitter and latency clocking with common reference clock signals for on-package input/output interfaces. A filter phase locked loop circuit in a master device on a first die provides a clock signal having a frequency of 2F. A local phase locked loop circuit in the master device on the first die is coupled with the filter phase locked loop to provide a clock signal to functional components of the master device through a local clock divider circuit to provide a clock signal of F to the functional components. A remote phase locked loop circuit in a slave device on a second die is coupled with the filter phase locked loop to provide a clock signal to one or more functional components of the slave device through a local clock divider circuit to provide a clock signal of F to the functional components.
