Claim 11:
12. The apparatus of claim 11, wherein calibration of the Rrx_d comprises:
adjusting a resistance of the Rrx_d over a range having multiple resistance values;
measuring, at the multiple resistance values, a peak amplitude of a training pattern signal received at the device receiver that is transmitted by the host transmitter; and
determining a resistance value among the multiple resistance values that yields a maximum peak amplitude of the training pattern signal received at the device receiver,
wherein the calibrated Rrx_d has a resistance value that yields the maximum peak amplitude of the training pattern signal received at the device receiver; and
wherein calibration of the Rrx_h comprises,
adjusting a resistance of the Rrx_h over a range having multiple resistance values;
measuring, at the multiple resistance values, a peak amplitude of a training pattern signal received at the host receiver that is transmitted by the device transmitter; and
determining a resistance value among the multiple resistance values that yields a maximum peak amplitude of the training pattern signal received at the host receiver,
wherein the calibrated Rrx_h has a resistance value that yields the maximum peak amplitude of the training pattern signal received at the host receiver.
