If using a 27-MHz crystal, the lower frequency limit for this band is 392 MHz.
(2)
If using optional Manchester encoding, the data rate in kbps is half the baud rate.
(3)
The acceptable crystal tolerance depends on frequency band, channel bandwidth, and spacing. Also see design note

All measurement results are obtained using the EM430F6137RF900 with BOM according to tested frequency range (see
Table 48
