It can also be used for any other system with carrier frequencies ranging from 850 MHz to 930 MHz (e.
g.
for applications in the US 915 MHz ISM band).
The transmitter's carrier frequency fc is determined by the frequency of the reference crystal fref.
The integrated PLL synthesizer ensures that each RF value, ranging from 850 MHz to 930 MHz, can be achieved by using a crystal with a reference frequency according to: fref = fc/N, where N = 32 is the PLL feedback divider ratio.
