LDO CONFIGURATIONS
the LDO mode. So, pay attention to correctly set the part to reflect the physical implementation. Attention is also needed when bypassing LDOs
to make sure that internal circuits are not supplied with incorrect voltage levels.
EXAMPLE:
TDD operation using Tx1, Rx1, and external LOs.
The hardware power setup looks like Figure 280, where the pins for the Tx2 and Rx2 1 V and 1.3 V LO domains are tied to ground. The LDOs
powering these RF blocks, VANA2_1P0, and VANA2_1P3, are also tied to ground because they are not needed.
Figure 280. Standard Operating Config 0 and External LO Config and Rx1/Tx1 Power-Supply Config
When the external LO configuration and Rx1/Tx1 configuration are super-positioned onto the standard operating configuration, connect the
power supplies per Figure 281.
