ML3372 Low Power Narrowband FM IF

OPERATING CONDITIONS VCC = 4.0 Vdc, RFIn = 100 µV, fmod = 1.0 kHz, fdev = 3.0 kHz. ML3371 at f RF = 10.7 MHz (see Figure 11). Pin 1 Symbol OSC1 Internal Equivalent Circuit Description The base of the Colpitts oscillator. Use a high impedance and low capacitance probe or a “sniffer” to view the wave<.

ML3371 ML3372 www.DataSheet4U.com 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 amplifier, 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 rep.
