Product Description
The RF2514 is a monolithic integrated circuit intended for use as a low-cost
AM/ASK transmitter. The device is provided in a 4mmx4mm, 16-pin leadless chip
carrier 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 ISM bands. The integrated VCO, phase
detector, reference divider, and reference oscillator transistor require only the addi-
tion of an external crystal to provide a complete phase-locked oscillator. 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.
