The MC13025 is the complementary ETR Electronically Tuned Radio
front–end for the second generation MC13022 C–QUAM 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.

• Operates Over a Wide Range of Supply Voltages: 6.0 V

CC

to 10 V

CC

• Wideband AGC Voltage to RF Amp for Extended Dynamic Range

• Buffered VCO Output to Frequency Synthesizer

• No External RF Amp Needed for Most Home Stereo and

Portable Radios

• IF Drive Output Matches the MC13022 for Optimum Performance

• VCO Operates at Four Times Local Oscillator Injection Frequency
