Product Description

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/868MHz 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.
