Abstract
A receiver including recovery, error, and control modules. The recovery module: receives a data signal and an offset value; based on a coefficient, equalizes the data signal to generate an equalized signal; and generates a recovered signal based on the equalized signal. The recovered signal includes data recovered by the recovery module. The error module generates an error value based on a difference between the equalized signal and a threshold. The control module, based on the offset value, the recovered signal, and the error value: generates the coefficient; determines the threshold; and determines a characteristic of an eye diagram of the recovered signal. The recovered signal has a non-repeating pattern such that overlaid traces of the recovered signal are in a shape of an eye and provide the eye diagram. The overlaid traces include jitter. The control module generates the coefficient to reduce an amount of the jitter.
