    Abstract: A method that is for operating a serial protocol interface includes a communication device that is configured to exchange data over a communication link by sending output data on the communication link, and receiving input data on the communication link. The input data is synchronous with a clock signal generated at the communication device and propagated over the communication link. The method also includes initializing operation by sending the output data on the communication link at a first data rate, detecting a signal transition in the input data received on the communication link, and exchanging data over the communication link at a second data rate when the signal transition is detected, the second data rate being higher than the first data, with the exchanging of data at the second data rate synchronized as a function of the signal transition.

    Abstract: A method includes providing a reference clock signal having a reference period, providing a sampling clock signal having a sampling clock period shorter than the reference period of the reference clock signal, measuring the first subperiod as a first ratio of the first subperiod to the period of the sampling clock signal, measuring the second subperiod as a second ratio of the second subperiod to the period of the sampling clock signal, detecting a starting edge of a clock signal having a clock period greater than the reference period, producing a reconstructed reference signal based on the first ratio, the second ratio, and the detected starting edge, comparing the clock period of the clock signal with a period of the reconstructed reference signal to obtain a differential signal indicating a difference therebetween, and providing the differential signal to user circuitry for calibrating the clock signal.

    Abstract: In accordance with an embodiment, a method includes: producing a set of delayed replicas of a reference clock signal, wherein delayed replicas in the set of delayed replicas have respective signal edges delayed in time by a mutual time delay therebetween; producing a set of edge detecting signals comprising edge detecting signals indicative of respective distances of edges of delayed replicas in the set of delayed replicas from an edge of a clock signal having a clock period; selecting based on edge detecting signals in the set of edge detecting signals a delayed replica in the set of delayed replicas having a distance from the clock signal edge that is shorter than the distance from the clock signal edge of any other delayed replica in the set of delayed replicas.
