ADM-VPX3-9Z2 User Manual
V1.1 - 16th January 2020

3.7.2.2 MicroSD and eMMC Flash Memories

The ADM-VPX3-9Z2 can interface to either a MicroSD card (SD 2.0 standard at 3.3V) or an eMMC device (v4.5
at 1.8V).
The Switch SW4-7 determines which of the two interfaces is in use (as they share common MIO pins).
The uSD card should be fitted in socket U87.

3.7.2.3 PS DDR4 Memory

The PS side of the MPSoC is connected to 1 bank of DDR4-2400 SDRAM, 1GB x72, 8GB total + ECC

3.7.3 Ethernet Interfaces

The 9Z2 has two SGMII Serial Ethernet Interfaces at VPX connector P1. Both Ethernet Interfaces are connected
to the MPSoC PS.
Both interfaces have a Marvell 88E1512 PHY, connected to the PS via RGMII.
The Zynq PS MDIO interface is also connected to the VPX connector via buffers.
Each interface has three status LEDs. The functions of these are shown in

3.7.4 Serial COM Ports

There are two serial COM ports connected to VPX connector P1, as shown in Figure
COM2 uses RS-232 by default but may be configured for RS-485 operation. Please contact Alpha Data for
further details of the RS-485 mode.
