Advanced Digital Tuning System for Car Radio 840569

New semiconductor chips have been developed that will allow radio designers to reduce the chip count and gain performance advantages. One chip, the uPD1713G, contains a four bit CMOS microprocessor controller, prescaler, PLL, IF counters, I/O capability and direct AM and FM input. The uPC1296G contains an RF amplifier, mixer, oscillator, IF amplifier, AGC circuitry and signal meter output. These chips can be combined to make a three chip, digitally tuned AM car radio.
