MOTOROLA ANALOG IC DEVICE DATA
Low Power Narrowband FM IF
. . . includes oscillator, mixer, limiting amplifier, AFC, quadrature
discriminator, op/amp, squelch, scan control, and mute switch. The MC3359
is designed to detect narrowband FM signals using a 455 kHz ceramic filter
for use in FM dual conversion communications equipment. The MC3359 is
similar to the MC3357 except that the MC3359 has an additional limiting IF
stage, an AFC output, and an opposite polarity Broadcast Detector. The
MC3359 also requires fewer external parts. For low cost applications
requiring VCC below 6.0 V, the MC3361BP,BD are recommended. For
applications requiring a fixed, tuned, ceramic quadrature resonator, use the
MC3357. For applications requiring dual conversion and RSSI, refer to these
devices; MC3335, MC3362 and MC3363.
Low Drain Current: 3.6 mA (Typical) @ VCC = 6.0 Vdc
Excellent Sensitivity: Input Limiting Voltage
3.0 dB = 2.0
V (Typical)
Low Number of External Parts Required
For Low Voltage and RSSI, use the MC3371
