ML3372
Low Power
Narrowband FM IF
Legacy Device: Motorola MC3371, MC3372
The ML3371 and ML3372 perform single conversion FM
reception and consist of an oscillator, mixer, limiting IF amplifi-
er, quadrature discriminator, active filter, squelch switch, and
meter drive circuitry. These devices are designed for use in FM
dual conversion communication equipment. The ML3371/ML3372
are similar to the Motorola MC3361/MC3357 FM IFs, except
that a signal strength indicator replaces the scan function control-
ling driver which is in the MC3361/MC3357. The ML3371 is
designed for the use of parallel LC components, while the
ML3372 is designed for use with either a 455 kHz ceramic dis-
criminator, or parallel LC components.
These devices also require fewer external parts than earlier
products. The ML3371 and ML3372 are available in dual–in–line
and surface mount packaging.
• Wide Operating Supply Voltage Range: VCC = 2.0 to 9.0 V
• Input Limiting Voltage Sensitivity of –3.0 dB
• Low Drain Current: ICC = 3.2 mA, @ VCC = 4.0 V,
Squelch Off
• Minimal Drain Current Increase When Squelched
• Signal Strength Indicator: 60 dB Dynamic Range
• Mixer Operating Frequency Up to 100 MHz
• Fewer External Parts Required than Earlier Devices
• Operating Temperature Range TA = –30° to +70°C
