Abstract: Techniques are described to adaptively adjust the equalizer settings of each transmitter in a transmitter-receiver pair. The transmitter-receiver pair can be used at least with implementations that comply with 40GBASE-CR4 or 100GBASE-CR10. For implementations that comply with 40GBASE-CR4, equalizer settings of four transmitters may be independently established.

Abstract: In one embodiment, the present invention includes an apparatus having a digital signal processor (DSP) coupled to receive a digitized signal. The DSP may be controlled to perform a timing recovery mechanism that implements a Mueller and Müller (MM)-based algorithm to generate a sensor output responsive to the digitized signal, where the incoming signal is non-linearly precoded in a transmitter from which the signal is received. Other embodiments are described and claimed.
