PURPOSE: A signal receiving device of a digital television with an asynchronous timing recovery circuit is provided to recover timing by using data instead of segment synchronization data. CONSTITUTION: A signal receiving device of a digital television with an asynchronous timing recovery circuit comprises a tuner portion(100), a crystal oscillation portion(310), an analog/digital conversion portion, an interpolator(410), a match filter(420), an error controller(430), and a numerical control oscillator(440). The tuner portion generates an intermediate frequency signal y tuning a high frequency signal. The crystal oscillation portion generates a sampling signal with a constant frequency. The analog/digital conversion portion converts the intermediate frequency signal to a digital signal. The interpolator generates a synchronous sample value by interpolating the digital signal. The match filter generated a timing correction signal. The error controller controls an interpolated number of the interpolator. |
