The AXM-VFX-EDK has a standard 34 pin double row 0.1” header for
front I/O. The I/O are LVTTL/CMOS compatible. These pin connections
can emulate the 30 differential channels on the AXM-D02 and AXM-D04
models and the 22 differential channels on the AXM-D03 model using
LVTTL signaling. Refer to the Differential I/O Register section for further
information. Front I/O connections are listed in Table 2.1.
The AXM-VFX-EDK front I/O also includes the standard Xilinx 14-pin
2mm JTAG header. This header can be used to directly program the FPGA
or to interface with the FPGA debug software ChipScope®. The pin
connections are shown in table 2.2.
In addition, the AXM-VFX-EDK contains 12 auxiliary pins that are routed
to two 8 pin SIP patterns on the board. Note that these are not front panel
I/O connections. Due to height restrictions SIP sockets are not installed.
This allows for full end user customization. These pins correspond to the 12
channels of Digital I/O on the AXM-D03 module. Refer to the Digital I/O
Register section for further information. The connections are listed in table
2.3.
Lastly, the AXM-VFX-EDK contains two right angle 9-pin DSUB or DB9
sockets that are routed to two UARTs on the PMV-VFX board. The
connections are listed in table 2.4.
Refer to drawing 4502-107, located at the end of this manual, for I/O pin
locations on the AXM-VFX-EDK.
