Television tuner having simple layout and capable of receiving FM broadcast signals without interference

摘要

A television tuner includes a mixer circuit for receiving a television signal or an FM signal, and a local oscillator circuit for generating an oscillation signal received by the mixer circuit. When the television signal is received, a television intermediate-frequency signal is generated by the mixer circuit. When the FM broadcast signal is received, an FM intermediate-frequency signal having a frequency converted to about 10.7 MHz is generated by the mixer circuit.
