Device and method for tracking a phase error in a digital TV receiver, wherein a phase noise compensated I signal is subtracted from I level reference signals of VSB signal, to obtain an error of the I signal, a sign of the Q signal having a phase noise thereof compensated is multiplied to the error of the I signal from the error determining part, to estimate a basic phase error, and a phase error compensating area is determined, a preset constant `.alpha.` is multiplied to the basic phase error to provide a final phase error in the determined phase error compensating area, and the basic phase error is provided as it is as the final phase error in other areas, thereby estimating the phase error more accurately.
