Abstract

Aspects of the embodiments are directed to systems, methods, and apparatuses to determine transmission equalization coefficients (TxEQs) for one or more lanes of a high speed serial link. Embodiments include determining a jitter tolerance for each TxEQ of a plurality of TxEQs for a lane of the link. The jitter tolerance for each TxEQ for the lane is based on a level of jitter induced on the lane to detect a number of errors on the lane; determining a voltage (VOC) margin for each TxEQ for the lane, wherein the voltage margin for the lane is based on a voltage corners test applied to the lane to detect a number of errors on the lane at a high voltage point and a low voltage point; determining a TxEQ that provides maximum jitter tolerance and based on the determined lowest voltage margin; and using the TxEQ for the lane during operation.
