10.2 Basic System Clocks

TClock

TClock (transmit clock) clocks the output registers of an external agent,*1 and can be a global system clock for any other logic in the external agent.

TClock is the same frequency as SClock. When SyncIn is shorted to SyncOut, the edges of TClock align precisely with the edges of SClock and MasterClock.

When a delay is added between SyncIn and SyncOut, the TClock at the pins leads SClock (and thus MasterClock) by the same amount of delay.

If the delay between SyncIn and SyncOut is matched to an external delay between TClock at the processor and TClock at the external logic, the TClock at the external logic aligns to SClock and MasterClock.
