MC3362 Datasheet, PDF (1/8 Pages) Motorola, Inc – LOW–POWER DUAL CONVERSION FM RECEIVER

Low-Power Narrowband
FM Receiver
. . . includes dual FM conversion with oscillators, mixers, quadrature
discriminator, and meter drive/carrier detect circuitry. The MC3362 also has
buffered first and second local oscillator outputs and a comparator circuit for
FSK detection.
• Complete Dual Conversion Circuitry
• Low Voltage: VCC = 2.0 to 6.0 Vdc
• Low Drain Current (3.6 mA (Typical) @ VCC = 3.0 Vdc)
• Excellent Sensitivity: Input Voltage 0.6 µVrms (Typical)
for 12 dB SINAD
• Externally Adjustable Carrier Detect Function
• Low Number of External Parts Required
• Manufactured Using Motorolais MOSAICr Process Technology
• MC13135 is Preferred for New Designs
