MC13025
Electronically Tuned Radio
Front End
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 VCC to 10 VCC
• 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
