A tuner integrated circuit includes two mixer circuits (11, 12), an IF amplifier circuit, three oscillation circuits, a PLL circuit (17), and a reference oscillation circuit (19). A plurality of terminals are provided at two sides of the tuner integrated circuit and are connected to these elements. Among the terminals, at least an oscillator connecting terminal No. 7 for connecting an externally provided oscillator to the reference oscillation circuit, power supply terminal No. 8 through which a power supply voltage is supplied, and ground terminal No. 6 connected to a ground are provided at one side of the tuner integrated circuit. Power supply terminal No. 8 and ground terminal No. 6 are disposed adjacent to oscillator connecting terminal No. 7 such that they sandwich terminal No. 7 therebetween. <IMAGE> |
