鈥?Local Oscillator Source
鈥?Remote Keyless Entry
Product Description
The RF2514 is a monolithic integrated circuit intended for
use as a low-cost AM/ASK transmitter. The device is pro-
vided 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 addition of an exter-
nal 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 dis-
ables the transmitter output when the PLL is out-of-lock.
