each BANK of FPGA, including BANK0, BANK13~16, BANK34~35. On AC7200 FPGA core
board, BANK34 and BANK35 need to be connected to DDR3, the voltage connection
of BANK is 1.5V, and the voltage of other BANK is 3.3V. The VCCO of BANK15 and
BANK16 is powered by the LDO, and can be changed by replacing the LDO chip.
VMGTAVCC is the supply voltage of the FPGA internal GTP transceiver, connected
to 1.0V; VMGTAVTT is the termination voltage of the GTP transceiver, connected
to 1.2V.
The Artix-7 FPGA system requires that the power-up sequence be powered by
VCCINT, then VCCBRAM, then VCCAUX, and finally VCCO. If VCCINT and VCCBRAM
have the same voltage, they can be powered up at the same time. The order of
power outages is reversed. The power-up sequence of the GTP transceiver is
VCCINT, then VMGTAVCC, then VMGTAVTT. If VCCINT and VMGTAVCC have the same
voltage, they can be powered up at the same time. The power-off sequence is
just the opposite of the power-on sequence.

which are used to connect
with the VCCIN power supply (+5V) and ground on the carrier board, extend the
normal IOs of the FPGA. It should be noted here that 15 pins of CON1 are
connected to the IO port of BANK34, because the BANK34 connection is connected
to DDR3. Therefore, the voltage standard of all IOs of this BANK34 is 1.5V.

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.
Power Supply on core board schematic
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:

Because the power supply of Artix-7 FPGA has the power-on sequence requirement, in the circuit design, we have designed according to the power requirements of the chip, and the power-on is 1.0V->1.8V->(1.5 V, 3.3V, VCCIO) and 1.0V-> MGTAVCC -> MGTAVTT, the circuit design to ensure the normal operation of the chip.

Part 3.2: Gigabit Ethernet Interface
The AX7203 FPGA development board provides users with 2-channel
Gigabit network communication service through the Micrel KSZ9031RNX
Ethernet PHY chip. The KSZ9031RNX chip supports 10/100/1000 Mbps
network transmission rate and communicates with the FPGA through the GMII
interface. KSZ9031RNX supports MDI/MDX adaptation, various speed
adaptations, Master/Slave adaptation, and support for MDIO bus for PHY
register management.
The KSZ9031RNX will detect the level status of some specific IOs to
determine their working mode after powered on. Table 3-1-1 describes the
default setup information after the GPHY chip is powered on.

connected to the FPGA in differential signals, and the single channel
communication rate can be up to 5G bit bandwidth. The PCIe reference clock is
provided to the AX7203 FPGA development board by the PCIe slot of the PC with
a reference clock frequency of 100Mhz.

Part 3.6: SD Card Slot
The SD card (Secure Digital Memory Card) is a memory card based on the
semiconductor flash memory process. It was completed in 1999 by the Japanese
Panasonic-led concept, and the participants Toshiba and SanDisk of the United
States conducted substantial research and development. In 2000, these
companies launched the SD Association (Secure Digital Association), which has
a strong lineup and attracted a large number of vendors. These include IBM,
Microsoft, Motorola, NEC, Samsung, and others. Driven by these leading
manufacturers, SD cards have become the most widely used memory card in
consumer digital devices.
The SD card is a very common storage device. The extended SD card supports SPI
mode and SD mode. The SD card used is a MicroSD card. The schematic diagram is
shown in Figure 3-6-1.

Part 3.9: Expansion Header
The carrier board is reserved with two 0.1inch spacing standard 40-pin
expansion ports J11 and J13, which are used to connect the ALINX modules or
the external circuit designed by the user. The expansion port has 40 signals,
of which 1-channel 5V power supply, 2-channel 3.3 V power supply, 3-channle
ground and 34 IOs. Do not directly connect the IO directly to the 5V device to
avoid burning the FPGA. If you want to connect 5V equipment, you need to
connect level conversion chip.
A 33 ohm resistor is connected in series between the expansion port and the
FPGA connection to protect the FPGA from external voltage or current. The
circuit of the expansion port (J11) is shown in Figure 3-9-1.

Part 3.10: JTAG Interface
A JTAG interface is reserved on the AX7203 FPGA carrier board for downloading
FPGA programs or firmware to FLASH. In order to prevent damage to the FPGA
chip caused by hot plugging, a protection diode is added to the JTAG signal to
ensure that the voltage of the signal is within the range accepted by the FPGA
to avoid damage of the FPGA chip.

Part 3.11: XADC interface (not installed by default)
The AX7203 carrier board has an extended XADC connector interface, and the
connector uses a 2×8 0.1inch pitch double-row pin. The XADC interface extends
three pairs of ADC differential input interfaces to the 12-Bit 1Msps analog-
to-digital converter of the FPGA. One pair of differential interfaces is
connected to the dedicated differential analog input channel VP/VN of the
FPGA, and the other two pairs are differentially connected to the auxiliary
analog input channels (analog channel 0 and analog channel 9). Figure 3-11-1
shows an anti-aliasing filter designed for three differential XADC inputs.
