RF2512
UHF TRANSMITTER
• Single- or Dual-Channel LO Source
• FM/FSK Transmitter
• Wireless Data Transmitters
• 433/868/915MHz ISM Band Systems
• Wireless Security Systems
The RF2512 is a monolithic integrated circuit intended for
use as a low-cost frequency synthesizer and transmitter.
Thedeviceis providedina 24 pinSSOP package andis
designed to provide a phased locked frequency source
for use in local oscillator or transmitter applications. The
chip can beusedinFM or FSK applications in theU.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.
• Fully Integrated PLL Circuit
• 15mW Output Power at 433MHz
• 2.7V to 5.0V Supply Voltage
• Low Current and Power Down Capability
• 300MHz to 1000MHz Frequency Range
• Narrowband and Wideband FM
