RF2917 11 Typical Applications Wireless Meter Reading Keyless Entry Systems 433/868/915MHz ISM Band Systems Remote Data Transfers Wireless Security Systems 433/868/915MHZ FM/FSK RECEIVER Product Description -A- The RF2917 is a monolithic integrated circuit intended for use as a low cost FM or FSK receiver. The device is provided in 32-lead plastic packaging and is designed to provide 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 reference 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. 7.00 + 0.20 sq. 0.15 0.05 0.50 0.22 + 0.05 1.40 + 0.05 Dimensions in mm. 5.00 + 0.10 sq. 7° MAX 0° MIN 0.60 + 0.15 0.10 0.127 Optimum Technology Matching® Applied ü Package Style: LQFP-32_5x5 Si BJT Si Bi-CMOS RESNTR- GaAs HBT SiGe HBT LOOP FLT RESNTR+ GaAs MESFET Si CMOS Features 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 21 RSSI 20 MUTE 22 FM OUT 11 TRANSCEIVERS 32 DC BIAS RX IN 2 PD 25 26 29 Phase Detector & Charge Pump 30 OSC B 31 OSC E LNA OUT 4 Prescaler ÷ 64 MIX IN 6 Linear RSSI M...
