The PD17006AGF-011 is a 4-bit CMOS microcontroller for digital tuning and can receive European FM, MW, and LW bands. It contains a prescaler (150 MHz MAX.), PLL frequency synthesizer, and IF counter. This microcontroller supports European Radio Data System (RDS) and implements various RDS functions, so that it can configure with a single chip a high-performance FM, MW, or LW tuner such as that for luxury automobile stereo systems. In addition, an RDS decoder is realized as a software library, so that the system using the PD170006AGF011 can eliminate one IC chip as compared with existing systems.
