Tuner for receiving digital television signals

摘要

Described herein is a digital television signal receiving tuner capable of simplifying the mounting and placement thereof onto a motherboard and preventing interference with the tuner by harmonic signals included in clock signals sent from a clock circuit. The digital television signal receiving tuner comprises a signal receiver (2) for frequency-converting a television signal to a first intermediate frequency signal corresponding to a television intermediate frequency circuit (3) for frequency-converting the first intermediate frequency signal output from the signal receiver to a second intermediate frequency signal lower in frequency than the first intermediate frequency signal and an analog/digital converter circuit (4) for converting the second intermediate frequency signal output from the intermediate frequency circuit to a digital signal, and wherein a clock circuit (5) for generating a clock signal for sampling the second intermediate frequency signal by the analog/digital converter circuit is incorporated in the tuner. <IMAGE>
