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 425 MHz to 445 MHz, can be achieved by using a crystal with a reference frequency according to: fref = fc/N, where N = 16 is the PLL feedback divider ratio.
