Abstract
The present invention relates to the detection and compensation technologies of the sampling frequency tolerance for use in the data frame synchronized sampling time restoration circuit. The feature of the invention is the dual loop confidence counter for detection of tolerance in frequencies for conversion into frequency tolerance compensation signals. After completing the compensation of frequency tolerance. The voltage control oscillator oscillates in the neighborhood of the signal sampling frequency. With minimum tolerance in frequency, the locking circuitry would be made in less stable variation. Thanks to this frequency tolerance compensation technology, the sampling time restoration circuit would have a larger frequency range and less stability variation. The invention is applicable on restoration of the communication system sampling sequence of all synchronized code having data frames, such as GA-HDTV signal transmission.
