Note 6: Power settings can be used with OQPSK-RC-{250,500}. Spectral side lobes
remain < -36 dBm / 100 kHz measured with a RMS detector outside Fc ± 1 MHz.
Note 7: Power settings can be used with OQPSK-RC-{250,500,1000}. Spectral side
lobes remain < -36 dBm / 100 kHz measured with a RMS detector outside Fc ± 1 MHz.
Values of Table 7-15 are based on a mode dependent setting of GC_TX_OFFS
(register 0x16, RF_CTRL_0) which is shown in Table 7-16.

The North American mapping table is optimized for lowest supply current. The more
relaxed spectral side lobe requirements of the IEEE 802.15.4 standard are fulfilled.
The EU1 and EU2 mapping tables take into account that linearity is needed to keep the
out-of-band spurious emissions below the ETSI requirements, refer to [5]. Regulatory
requirements with respect to power density (depending on the frequency band used)
are not considered, refer to [6].
