Abstract
An apparatus for performing decision feedback equalizer (DFE) adaptation control is provided. The apparatus includes arithmetic circuits, slicers, sample and hold circuits, a phase detector and a control circuit for related operations. The control circuit generates parameters at least according to an error sample value and data sample values, and dynamically updates the parameters based on at least one predetermined rule to perform the DFE adaptation control. The parameters include a first parameter, another parameter and a factor adjustment parameter. Regarding at least one data pattern, the control circuit selectively replaces the error sample value with a predetermined value according to whether a temporary storage value of the error sample value conforms to a predetermined condition to control the other parameter and the first parameter, in order to prevent triggering an unstable effect and thereby prevent abnormal operations.
