Product Description

The RF2917 is a monolithic integrated circuit intended for

use as a low cost FM or FSK receiver. The device is pro-

vided in 32-lead plastic packaging and is designed to pro-

vide a fully functional FM receiver. The chip is intended

for analog or digital applications in the North American

915MHz ISM band and European 433MHz and 868 MHz

ISM bands. The integrated VCO, ÷64 prescaler, and ref-

erence oscillator require only the addition of an external

crystal to provide a complete phase-locked oscillator for

single channel applications. The selection of linear FM

output or digital FSK output is done with the mute pin.
