1. A circuit comprising:
a plurality of pulse amplitude modulation drivers configured to receive different input signal pairs and corresponding ones of a plurality of drive values, and generate corresponding ones of a plurality of driven input signal pairs, wherein the plurality of drive values includes a first drive value and additional ones of the plurality of drive values that are a function of the first drive value and corresponding ones of a number of drive factors; and
a source, coupled to the plurality of pulse amplitude modulation drivers, and configure to generate an output optical signal as a function of the plurality of driven input signal pairs, wherein the optical signal output varies over time as a function of an operating temperature of the source and the plurality of drive values are configured to maintain linearity of eye height values of the output optical signal.
