Part 2.12: Power Supply

The AC7200 FPGA core board is powered by DC5V via carrier board, and
it is powered by the J3 interface when it is used alone. Please be careful not to
supply power by the J3 interface and the carrier board at the same time to
avoid damage. The power supply design diagram on the board is shown in.
The development board is powered by +5V and converted to +3.3V, +1.5V,
+1.8V, +1.0V four-way power supply through four DC/DC power supply chip
TLV62130RGT. The output current can be up to 3A per channel. VCCIO is
generated by one LDOSPX3819M5-3-3. VCCIO mainly supplies power to
BANK15 and BANK16 of FPGA. Users can change the IO of BANK15,16 to
different voltage standards by replacing their LDO chip. 1.5V Generates the
VTT and VREF voltages required by DDR3 via TI's TPS51200. The 1.8V power
supply MGTAVTT MGTAVCC for the GTP transceiver is generated by TI's
TPS74801 chip. The functions of each power distribution are shown in the
following table:
