3.3. Power Supply

This board operates from single DC 3.3 V power supply from CNA and CNB.
Internally required 1.8[V], 1.2[V] and 0.9[V] are generated by on-board voltage
regulators.
The external power supply should be sufficient and stabilized. Please do not apply
over 3.3V voltage.
VCCIO in BANK B is not connected to 3.3V. Please input given voltage from CNB.
For more details, please refer to circuit schematics and FPGA data sheet.
