kBaud
The data rate is programmable.
See section 10 on page 27 for
details.
NRZ or Manchester encoding can
be used. 153.6 kBaud equals
153.6 kbps using NRZ coding
and 76.8 kbps using Manchester
coding. See section 9.2 on page
25 for details
Minimum data rate for OOK is 2.4

Harmonics are measured as
EIRP values according to EN 300

and SMAFF-868 from R.W.
Badland) plays a part in
attenuating the harmonics.
