ABSTRACT:
A physical layer of an Ethernet network device includes first, second, third and fourth terminals. An autonegotiation circuit includes an autonegotiation wait timer having an autonegotiation wait period. An auto-crossover circuit selectively configures the first and second terminals as one of a transmitter and a receiver and the third and fourth terminals as the other of the transmitter and receiver. The auto-crossover circuit includes a sample timer having a sample timer period that has a value that is greater than or equal to the autonegotiation wait period. The auto-crossover circuit includes a random number generator that communicates with the sample timer and generates n random numbers. The sample timer selects one of n sample timer periods based on the generated random number. The n sample timer periods have values that are greater than or equal to the autonegotiation wait period.
