CC2400
30 Data Rate Programming
The supported over-the-air data rates are
1Mbps, 250kbps and 10kbps. The data
rate is programmable via the GRDEC
register.
Supported channel filter bandwidths and
data rates are shown in the following
table.
Figure 19 shows how sensitivity varies as
a function of frequency offset between the
transmitter and the receiver for various
data rates. It is possible to tolerate even
larger offsets by making use of the AFC
feature; please see page 42 for further
details.
