RF2512

RF2512 11 Typical Applications Single- or Dual-Channel LO Source FM/FSK Transmitter Wireless Data Transmitters 433/868/915MHz ISM Band Systems Wireless Security Systems UHF TRANSMITTER Product Description The RF2512 is a monolithic integrated circuit intended for use as a low-cost frequency synthesizer and transmitter. The device is provided in a 24 pin SSOP package and is designed to provide a phased locked frequency source for use in local oscillator or transmitter applications. The chip can be used in FM or FSK applications in the U.S. 915MHz ISM band and European 433MHz or 868MHz ISM band. The integrated VCO, dual-modulus/dual-divide (128/129 or 64/65) prescaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked oscillator. A second reference oscillator is available to support two channel applications. 0.157 0.150 0.0098 0.0040 1 0.344 0.337 0.012 0.008 0.025 0.0688 0.0532 0.2440 0.2284 8°MAX 0°MIN 0.050 0.016 0.0098 0.0075 Optimum Technology Matching® Applied ü Package Style: SSOP-24 Si BJT Si Bi-CMOS GaAs HBT SiGe HBT GaAs MESFET Si CMOS Features Fully Integrated PLL Circuit 15mW Output Power at 433MHz 11 TRANSCEIVERS LOOP FLT RESNTR+ RESNTR- LVL ADJ OSC B1 OSC B2 MOD IN VREF P OSC E 2.7V to 5.0V Supply Voltage Low Current and Power Down Capability 300MHz to 1000MHz Frequency Range Narrowband and Wideband FM 7 Gain Control 16 18 20 23 13 3 2 1 TX OUT 8...
