Abstract
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate one or more first control signals in response to a reference impedance. The second circuit may be configured to operate in (i) a first mode in response to a first state of a second control signal and (ii) a second mode in response to a second state of the second control signal. When the second circuit is in the first mode, an output impedance of the second circuit may be adjusted in response to the one or more first control signals and the one or more first control signals may be presented at a first input/output of the second circuit. When the second circuit is in the second mode, the output impedance of the second circuit may be adjusted in response to one or more third control signals received at a second input/output of the second circuit.
