Claim:
1. A method of operating an integrated circuit, the method comprising: at rate detection circuitry, receiving a reference clock signal from external circuitry; with the rate detection circuitry, determining a frequency of the reference clock signal; with clock generation circuitry, generating a receiver clock signal for receiver circuitry on the integrated circuit based on the determined frequency of the reference clock signal; with a transceiver configuration circuit that is coupled between the rate detection circuitry and the receiver circuitry, configuring the receiver circuitry based at least on the determined frequency of the reference clock signal; with the transceiver configuration circuit, configuring transmitter circuitry on the integrated circuit based at least on the determined frequency of the reference clock signal; and with a clock configuration circuit that is separate from the transceiver configuration circuit and the clock generation circuitry and that is coupled between the rate detection circuitry and the clock generation circuitry, configuring the clock generation circuitry based at least on the determined frequency of the reference clock signal.
