VmodMIB™
Reference Manual
Revision: January 5, 2011
Overview
The Digilent Vmod Module Interface Board
(VmodMIB) is a simple solution for interfacing
additional peripheral modules and HDMI
devices to VHDCI-equipped Digilent system
boards.
Features include:
• VHDCI peripheral board connector
• Four HDMI and five 12-pin Pmod™
connectors
Functional Description
The VmodMIB is an expansion board that
connects to the VHDCI connector on Digilent
system boards and provides additional Pmod
and HDMI connections.
Power Connections
The VmodMIB provides two power busses and
a ground bus. The two power busses are
labeled VCC and VU. These two busses are
made available at each connector position on
the board. There is also a ground plane that
connects the ground pins from all connectors.
The usual Digilent convention is to power the
VCC bus at 3.3V and the VCCFX2 bus at 5.0V.
However, depending on the system board
connected and the power supply used, other
voltages may be present. Use caution when
using any voltage other than 3.3V on the VCC
bus. Most Digilent system boards will be
damaged if the voltage on the VCC bus is
greater than 3.3V.

68 Pin, VHDCI Connector
VHDCI connector J1 is provided on one side of
the board for connection to Digilent system
boards, like the Genesys™ and Atlys™, which
contain a VHDCI-style connector. The Digilent
VHDCI connector signal convention provides
for 40 general-purpose I/O signals.
The 40 general-purpose I/O signals from the
VHDCI connector are brought out to the Pmod
and HDMI connectors. See Table 1 for a
description of the relationship between the
VHDCI connector pins and the signal names,
Table 2 for the relationship between signal
names and Pmod pins and Table 3 for the
relationship between signal names and HDMI
pins.
