Abstract: A high-speed data communication interface includes first and second lanes. The first lane includes a first transmitter coupled to send a first data signal to a first receiver via a first channel. The second lane includes a second transmitter coupled to send a second data signal to a second receiver via a second channel. The first channel injects crosstalk into the second channel. The second transmitter sets a duty cycle adjuster input to adjust a duty cycle of the second data signal to reduce the crosstalk.

Abstract: An information handling system includes a dual in-line memory module (DIMM) and a memory controller coupled to the DIMM via a data bus. The memory controller determines that a first lane of a byte group of the data bus is more susceptible to crosstalk than a second lane of the byte group, determines a first performance level of the first lane, changes a delay (D) of a third lane of the byte group, the third lane being adjacent to the first lane, and determines that a second performance level of the first lane is different from the first performance level in response to delaying the third lane.

Abstract: An information handling system includes a memory controller and a dual in-line memory module (DIMM) coupled to the memory controller by a memory channel. The memory channel includes a plurality of single-ended multi-drop lanes arranged in a byte group. The information handling system determines, for each lane in the byte group, a tap setting for an associated decision feedback equalizer (DFE) of each lane. The information handling system further determines an average value for the tap settings for the lanes in the byte group, determines that a first tap setting for a first lane is different from the average value by greater than a threshold, and sets the first tap setting to the average value in response to determining that the first tap setting is different from the average value by greater than the threshold.
