AC7010B/AC7020B core board is powered by the carrier board, remove the 0Ω
resistor (R161) on the board. Please do not use other specifications of the
power supply to avoid damage to the core board.
The power supply design on
the core board is as follows:
Figure 3-1: Power Supply Schematic
The development board is powered by +5V, and is converted into +1.5V,
+1.8V, +1.0V three-way power supply through three DC/DC power supply chip
TLV62130RGT. Each output current can be up to 3A. The 3.3V, VCCIO34 and
VCCI35 power supplies are generated by the three LDOs “SPX3819M5-3-3”,
the VCCIO34 is powered by the BANK34 of ZYNQ, and the VCCIO35 is
powered by the BANK35 of ZYNQ. By replacing with other LDO chips, BANK34
and BANK35IO adapts to different voltage standards. +1.5V Generates VTT
and VREF voltages required by DDR3 via TI's TPS51200
