GENERAL DESCRIPTION
The RF65 is a highly integrated RF receiver capable of operation over a wide frequency range, including the 3 1 5 , 433,868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The RF65 offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. The RF65 is optimized for low power consumption while offering high sensitivity and channelized operation. TrueRF™ technology enables a lowcost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
