Frequency Shift Keying (FSK) Example
FSK operation requires an external input trigger signal at either MOD, TRIG1 or TRIG2 pin. In this
example, MOD pin is selected as the Trigger A source. A 20 kHz square-wave clock will be applied to
MOD pin to toggle the RF output to switch between 9600 MHz and 9604 MHz. That is, FSK deviation is 4
MHz.
