A data processing device that can eliminate interference symbol interference (ISI) of a transmitted data through a timing recovery circuit and ferret out a correct sampling time. It includes an analog-digital converter, a timing recovery device and a sync-word matching filter. The analog-digital converter is used for receiving an analog signal, sampling the analog signal at a sampling frequency, generating a series of sample values, and converting these sample values to a digital signal having a main cursor component, a pre-cursor interference component, and a post-cursor interference component. The post-cursor interference component has a plurality of post-cursor channel response. The timing recovery device is used for eliminating the post-cursor interference component in accordance with the digital signal, while retaining the first post-cursor channel response, and the main cursor component and the pre-cursor interference component to generate an output signal. The sync-word match filter estimates a timing error according to the output signal and adjusts the sampling frequency for optimization.
