Digital I/O with HERON-FPGA Modules

• Standard IP for each HERON-FPGA module
• VHDL sources so that you can add your own FPGA design
• Standard IP to provide custom I/O capability

HUNT ENGINEERING FPGA modules provide Digital I/O capability via one or more Digital I/O connectors on the module. The signals provided on the Digital I/O connectors are routed directly to the FPGA via series or parallel resistors for signal termination. The modules support the use of many different I/O standards depending on the capabilities of the Xilinx FPGA that is fitted to each module. They provide a variety of termination schemes varying from on-board parallel or series resistor networks or on-chip Digitally Controlled Impedance.
Single ended signalling is possible, as is differential signalling. When using a differential signalling standard such as LVDS for example, signals are paired on the connectors such that the associated positive and negative signal pairs can be used within the Xilinx^® FPGA.
This document details all of the issues involved in connecting to the Digital I/Os of your FPGA module including choice of termination scheme, I/O standard selection and differential signalling.
