Methods and systems for a reference clock

摘要

In at least some embodiments, a method comprises receiving an external card detection signal that indicates that a hot-pluggable card is coupled to a computer system and activating at least one reference clock signal of a scalable reference clock platform based on the external card detection signal. The method further comprises synchronizing clock signals embedded in data packets transmitted between the hot-pluggable card and the computer system with another clock signal based on the at least one reference clock signal.
