RF2514 transmitter

I want to use it in the Security Systems, and in the OOK mode.
what should I do ? use the pin 5(mod in)?
If my input is digital modulation , it will work in the OOK mode auto?

Hi,
Please refer to side 7, in the midle.
You will find it so:
It must be possible, but (if I`m right) you wish to drive in both sort of Modulated modus?
Then datasheed said us:
In OOK-modus you have to modulate the Ref-Oscillator directly(means you need a switch for put Pin 5 trough serial resistor to Vcc)!
Or in other modus you have to apply your modulation signal directly to Pin 5...
If you have digital mod-signal= you have 100% modulation, but you must limit these voltage!
You can read: "higher as 1.1V at pin5 may be damage the device"...
