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 902 to 928 MHz ISM band). The transmitter s carrier frequency f is determined by the frequency of the reference crystal f . The integrated PLL c ref synthesizer ensures that each RF value, ranging from 850 MHz to 930 MHz, can be achieved. This is done by using a crystal with a reference frequency according to: f = f /N, where N = 32 is the PLL feedback divider ratio. ref c Page 1 of 21 REVISION 013 - JUNE 14, 2017 3901072031 TH72031 868/915MHz FSK Transmitter Contents Features ..................................................................................................................................................... 1 Application Examples ................................................................................................................................. 1 Pin Description ........................................................................................................................................... 1 Ordering information ................................................................................................................................. 1 General Description ................................................................................................................................... 1 1.
