The MC13025 is the complementary ETR Electronically Tuned Radio frontend for the second generation MC13022 CQUAM AM stereo IF and decoder. The MC13025 provides a high dynamic range mixer, voltage controlled oscillator, and first IF that with the MC13022 and synthesizer form a complete digitally controlled AM stereo tuner system. This system in turn may drive a dual channel audio processor and high power amplifiers for car radio or home stereo applications. Other applications include portable radio "boom boxes", table radios and component stereo systems.
