The crystal frequency may be altered to produce any desired frequency within the 902MHz to 928MHz band.
Measured with no load on XO8 output pin.
Antenna load impedance = 400 .
The levels stated are supplied to a external series resistor in front of the DIN input pin
Output is an open collector.
Controllable with crystal parameters and external data filter.
