Abstract: A timing margin detecting circuit is provided. The timing margin detecting circuit comprises a delay element, receiving a first data signal and a first clock signal, configured to generate a second data signal and a second clock signal, wherein the second clock signal has a delay relative to the second data signal; a controller, configured to generate the control signal to control the delay of the second clock signal relative to the second data signal; a sampler, coupled to the delay element, configured to generate a sampled data signal according to the second data signal and the second clock signal; and a bit error rate determination circuit, coupled to the sampler, configured to determine whether the sampled data signal is the same as a predefined test pattern and generate a determination result accordingly; wherein the controller determines a timing margin according to the determination result.

Abstract: An integrated circuit for driving a display panel and an anti-interference method are provided. The integrated circuit includes a source driving circuit and an anti-interference circuit. The source driving circuit includes a receiving circuit configured to receive an input signal including image data and process the input signal based on at least one operation parameter to generate output data. The anti-interference circuit is coupled to the receiving circuit. The anti-interference circuit determines whether an interference event occurs to the input signal based on the input signal or the output data to obtain a determination result and determines whether to adjust the at least one operation parameter of the receiving circuit according to the determination result.
