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.
• Fully Monolithic Integrated Receiver
• 2.7V to 5.0V Supply Voltage
• Narrowband and Wideband FSK
• 300MHz to 1000MHz Frequency Range
• Power Down Capability
• Analog or Digital Output
