Product Description
The RF2516 is a monolithic integrated circuit intended for use as a low-
cost AM/ASK transmitter. The device is provided 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 transis-
tor 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 transmit-
ter output when the PLL is out-of-lock.
