Abstract: A phase predictor to accurately detect and predict the phase relationship between two clocks running at different frequencies. The phase relationship can be used to record the transmission and reception times of Ethernet frames transmitted over a transmission medium with very high accuracy.

Abstract: A PHY chip for a synchronous Ethernet system includes N network input/output (I/O) ports, a first external recovered clock input, a first recovered clock output, and a first clock multiplexer having a plurality of data inputs, a select input, and an output coupled to the first recovered clock output, at least one of the data inputs coupled to a first recovered clock from a respective one of the N network I/O ports, a first additional data input coupled to the first external recovered clock input.
