• Wireless Data Transmitters
• 433/868/915MHz ISM Band Systems
• Wireless Security Systems
UHF TRANSMITTER
Product Description
The RF2513 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.
