• Battery-Powered Portable Devices
The RF2915 is a monolithic integrated circuit intended for
use as a low cost FM transceiver. The device is provided
in 32-lead plastic TQFP packaging and is designed to be
used with a PLL IC to provide a fully functional FM trans-
ceiver. The chip is intended for digital (ASK, FSK, OOK)
applications in the North American 915MHz ISM band
and European 433MHz/868 MHz ISM band. The inte-
grated VCO has a buffered output to feed the RF signal
back to the PLL IC to form the frequency synthesizer.
Internal decoding of the RX ENABL and TX ENABL lines
allow for half-duplex operation as well as turning on the
VCO to give the synthesizer time to settle and complete
power down mode.
