RF2514
VHF/UHF TRANSMITTER
• 868MHz/915MHz ISM Band Systems
• Local Oscillator Source
• Remote Keyless Entry
• AM/ASK/OOK Transmitter
• Wireless Security Systems
The RF2514 is a monolithic integrated circuit intended for
use as a low-cost AM/ASK transmitter. The device is pro-
vided in a 4 mmx4mm, 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.
• Fully Integrated PLL Circuit
• Integrated VCO and Reference Oscillator
• 2.2V to 3.6V Supply Voltage
• Low Current and Power Down Capability
• 100MHz to 1000MHz Frequency Range
• Out-of-Lock Inhibit Circuit
