Table 13. Bill of materials for the application circuit in Figure 3. The PLL loop filter is
optimized for 38.4 kBaud data rate.
Note:
The PLL loop filter component values in
Table 13 (R2, R3, C6-C8) are optimized
for 38.4 kBaud data rate. The SmartRF
Studio software provides component
values for other data rates using the
equations on page 50.
In the CC1020EMX reference design,
which is also applicable for , CC1021
LQG15HS series inductors from Murata
have been used. The switch is SW-456
from M/A-COM.
