Notes:
ZC706 boards prior to Rev. 2.0 implemented different voltage regulators for VCCINT, VCCAUX/VCC1V8, VCC1V5_PL,
VADJ_FPGA/VADJ and VCC3V3_FPGA/VCC3V3. Refer to UG954 v1.3 and earlier, and to the schematic for the particular version
of the ZC706 board prior to Rev. 2.0. Notes on ZC706 boards prior to Rev. 2.0:
1. VCCINT is implemented utilizing 2xLMZ22008 8A components (U42, U43) in parallel which provides 16A capability.
2. The 1.8V rails are supplied from a LMZ22010 10A component (U98).
3. VCC1V5_PL and the 2.5V rails are supplied from TPS84621 6A components (U85, U86).
4. The 3.3V rails are supplied from a LMZ22010 10A component (U15).
