Notes:
1. The output voltages of regulators controlled by a UCD9248 can be reprogrammed using the Texas Instruments Fusion Digital Power
Designer application (www.ti.com/tool/fusion_digital_power_designer). However, extreme caution must be taken when
attempting to modify any of the onboard regulators. An incorrectly programmed regulator can damage onboard components.
2.
The UCD9248PFC (U11) at Address 54 monitors MGTAVCC, MGTAVTT, and MGTVCCAUX rail voltage and current levels
observed in real time using the Texas Instruments Fusion Digital Power Designer application (see
page
12). Transceiver supply voltages cannot be changed from this controller.
