Abstract: Methods and apparatuses for dynamically adjusting sync windows are described. A default sync window is set; a data signal is input; detecting if parts of the data signal within the sync window form a sync pattern; accumulating a count of the sync pattern within and without the sync window; and reducing the sync window when the count of sync pattern within the sync window achieves a first threshold value, and increasing the sync window when the count of the sync pattern outside the sync window achieves a second threshold value.

Abstract: A circuit for correcting a clock of a compact signal and a method therefor. The method comprises: receiving a data signal and a clock signal; and generating a sync pattern signal by using the clock signal to check the data signal. Then, a detection window signal according to a clock number during a timing of a last sync pattern signal and a first preset timing is generated, and the detection window signal having a second preset timing width. Finally, a clock of the sync pattern signal and the detection window signal are compared, and the clock signal is corrected.

Abstract: Method of dynamic adjusting the sync window of present invention including setting a default sync window; inputting a data signal once in a time; detecting if parts of the data signal within the sync window is a sync pattern; accumulating times of the sync pattern within and without the sync window; and reducing the sync window when times of sync pattern within the sync window achieving one threshold value, and increasing the sync window when times of sync pattern outside the sync window achieves another threshold value.
