In one embodiment, an integrated circuit is disclosed. The integrated includes a general purpose processor, an interface circuit, and a calibration adapter circuit. The general purpose processor circuit generates calibration test inputs based on user instruction. The analog interface circuit may include a calibration bus circuit. The calibration bus circuit may receive the calibration test input from the general purpose processor circuit. The calibration adapter circuit is coupled to the calibration bus circuit and the general purpose processor circuit and transmits the calibration test inputs to the calibration bus circuit.

An integrated circuit includes physical media attachment ('PMA') circuitry that includes two different kinds of transceiver channels for serial data signals. One kind of transceiver channel is adapted for transceiving relatively low-speed serial data signals. The other kind of transceiver channel is adapted for transceiving relatively high-speed serial data signals. A high-speed channel is alternatively usable as phase-locked loop ('PLL') circuitry for providing a clock signal for use by other high- and/or low-speed channels. A low-speed channel can alternatively get a clock signal from separate low-speed PLL circuitry.
