The µPD17012GF-058 is a CMOS LSI chip designed for use in FM/MW/LW tuners utilizing a PLL frequency

synthesizer design for worldwide applications.

The device incorporates a PLL frequency synthesizer controller, prescaler, and frequency counter. The device enables detachable stereo systems, and is ideal for use in electronic volume control circuits for automobile applications, high-performance FM/MW/LW tuners with a clock, and similar applications where compact dimensions are essential.
