Abstract
Described is an apparatus which comprises: a pre-driver coupled to a transmitter, the transmitter having a differential output; and a tuning circuit operable to couple to the differential output to tune the pre-driver of the transmitter according to a common mode noise signature of a common mode signal derived from the differential output.

An apparatus comprising:
- a pre-driver to receive input data and to generate outputs;
- a transmitter to receive outputs from the pre-driver, the transmitter having first and second outputs for coupling to a transmission media;
- and
- a tuning circuit coupled to the transmitter, the tuning circuit is operable to:
- couple itself to the first and second outputs;
- analyze signals on the first and second outputs;
- and
- adjust one or more circuits in the pre-driver according to the analysis.
