2.9 Power Supply

The power supply voltage of the AC7Z035B core board is DC5V, which is
supplied by connecting the carrier board. The schematic diagram of the power
supply design on the board is shown in Figure 2-9-1:

+5V generates a+1.0V ZYNQ core power supply through the DCDC power chip
MYMGK1R820FRSR, with an output current of up to 20A, which far meets the
current requirements of ZYNQ's core voltage. Then, +5V generates MGTAVTT, +1.5V,
+3.3V, and+1.5V through the DCDC chip ETA1471, generates the power supply of
MGTAVTT via DCDC chip ETA8156. +3.3V generates GTX auxiliary power
supply+1.8V through LDO chip SPX3819-1-8. The VTT and VREF voltages of DDR3 in
the PS and PL parts are generated by TPS51200. In addition, the IO power supply for
