Abstract
Examples relate to determining a sampling threshold of a receiver (e.g., SERDES receiver). In particular, the examples relate to determining an updated sampling threshold of the receiver based on a reference sampling threshold of the receiver. A controller may determine the reference sampling threshold based on the training sequence and determine an upper voltage level and a lower voltage level of a voltage range based on the reference sampling threshold of the receiver. The controller then narrows the voltage range based on upper voltage accumulated hit rate and a lower voltage accumulated hit rate to determine the updated sampling threshold of the receiver.
