Processor Sideband Signals

Intel® Xeon® Processor Scalable Family includes asynchronous sideband signals that provide asynchronous input, output or I/O signals between the processor and the platform or Platform Controller Hub. Details can be found in Table: Signal Groups and the applicable platform design guide.

All processor asynchronous sideband input signals are required to be asserted/ deasserted for a defined number of BCLKs in order for the processor to recognize the proper signal state, these are outlined in Processor Asynchronous Miscellaneous I/O DC Specifications and Processor Asynchronous Miscellaneous I/O AC Specifications. Refer to Signal Quality for applicable signal integrity specifications.
