Low Power Narrowband
FM Receiver
. . . includes dual FM conversion with Oscillators, Mixers, Quadrature
Discriminator, and Meter Drive/Carrier Detect Circuitry. The MC3335 also
has a comparator circuit for FSK detection.
• Complete Dual Conversion Circuitry
• Low Voltage: VCC = 2.0 to 6.0 Vdc
• Low Drain Current (Typical 3.6 mA with VCC = 3.0 Vdc)
• Excellent Sensitivity: – 3.0 dB Input Limiting = 0.7 µV
• Externally Adjustable Carrier Detect Function
• Separate Data Shaping Output Circuitry
• Data Rate Up to 35000 Baud Detectable
• 60 dB RSSI Range
• Low Number of External Parts Required
• Manufactured in Motorola′s MOSAIC^® Process Technology
• MC13135 is Preferred for New Designs
