Abstract: A method relates generally to a receiver. In such a method, a check of a clock and data recovery block of the receiver for a metastable state is performed. A phase input to a phase interpolator of the receiver is changed to cause the clock and data recovery block of the receiver to exit the metastable state within a time limit. To check for the metastable state, a phase difference in received data is determined, and the phase difference is determined to be less than a threshold for the clock and data recovery block being in the metastable state.

Abstract: Systems and methods for managing fast to slow links in a bus fabric. A pair of link interface units connect agents with a clock mismatch. Each link interface unit includes an asynchronous FIFO for storing transactions that are sent over the clock domain crossing. When the command for a new transaction is ready to be sent while data for the previous transaction is still being sent, the link interface unit prevents the last data beat of the previous transaction from being sent. Instead, after a delay of one or more clock cycles, the last data beat overlaps with the command of the new transaction.
