Abstract: A clock and data recovery device and a jitter tolerance enhancement method thereof are provided. The clock and data recovery device includes a clock and data recovery circuit and a jitter tolerance enhancement circuit. A data input terminal of the clock and data recovery circuit is suitable for receiving a data signal. The clock and data recovery circuit recovers the data signal to a clock. The jitter tolerance enhancement circuit is coupled to the data input terminal of the clock and data recovery circuit to receive the data signal. The jitter tolerance enhancement circuit detects a correlation between the data signal and the clock and correspondingly adjusts a loop gain of the clock and data recovery circuit according to the correlation.

Abstract: An integrated circuit for driving a display panel and an anti-interference method are provided. The integrated circuit can include 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 can determine 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.
