transmitted signal for demodulation to be
performed reliably and robustly.
The frequency deviation is programmed with
the DEVIATION_M and DEVIATION_E values
in the DEVIATN register. The value has an
exponent/mantissa form, and the resultant
deviation is given by:

Amplitude Modulation
The amplitude modulation supported by CC113L
is On-Off Keying (OOK).
When using OOK, the AGC settings from the
SmartRF Studio [4] preferred FSK
settings are not optimum. DN022 [8] gives
guidelines on how to find optimum OOK
settings
from
the
preferred
settings
in
setting has no effect when using OOK.
17 Received Signal Qualifiers and RSSI
CC113L has several qualifiers that can be used
to increase the likelihood that a valid sync
word is detected:
Sync Word Qualifier
RSSI
Carrier Sense
17.1
Sync Word Qualifier
If sync word detection is enabled in the
filling the RX FIFO and perform the packet
filtering described in Section 15.2 before a
valid sync word has been detected. The sync
word
qualifier
mode
is
set
by
MDMCFG2.SYNC_MODE and is summarized in
described in Section 17.3.
