1. A system comprising:

  • a processor; and

    an input/output (I/O) link, coupled to the processor, to compensate for process, voltage, and temperature (PVT) effects, the link including;

    execution logic to determine first and second compensation codes; and

    a driving circuit, coupled to the execution logic, to control impedance based on the first and second compensation codes;

    wherein (a) the first code corresponds to a first variable resistance code for a variable resistive element, a first variable capacitance code for a variable capacitive element, and a first PVT condition; and

    (b) the second code corresponds to a second variable resistance code for the variable resistive element, a second variable capacitance code for the variable capacitive element, and a second PVT condition unequal to the first PVT condition.
