RoHS Compliant & Pb-Free Product
Typical Applications
• 315/433MHz Band Systems
• Local Oscillator Source
• Part 15.231 Applications
Product Description
The RF2516 is a monolithic integrated circuit intended for
use as a low-cost AM/ASK transmitter. The device is pro-
vided in a 16-pin QSOP-16 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 applications in the North American and European
VHF/UHF bands. The integrated VCO, phase detector,
prescaler, and reference oscillator transistor require only
the addition of an external crystal to provide a complete
phase-locked loop. In addition to the standard power-
down mode, the chip also includes an automatic lock-
detect feature that disables the transmitter output when
the PLL is out-of-lock.
