Abstract
A data receiving circuit includes a decision feedback equalization circuit, configured to perform decision feedback equalization on a receive circuit based on a feedback signal to adjust a first output signal and a second output signal, where the feedback signal is obtained based on previously received data, the decision feedback equalization circuit responds to a first control signal group and a second control signal group to change an adjustment capability, the first control signal group corresponds to one data port corresponding to a data signal, and the second control signal group corresponds to all data ports. The capability of the decision feedback equalization circuit can be controlled to adjust the first output signal and the second output signal, where the adjustment capability has a wide adjustable range, to reduce impact of intersymbol interference of received data on the data receiving circuit.
