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 of 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.
3. For information on XADC see UG480, 7 Series FPGAs XADC Dual 12-Bit 1MSPS Analog-to-Digital Converter User Guide.

Using External Power Sources

Callout 18,
Each voltage rail for the FPGA logic and GTX transceivers has an associated jack (or jacks)
that can be used to provide power from an external source
binding posts that accept standard banana plugs.
