Introduction
1
The THDB-HTG board is designed to convert a High-Speed Terasic connector (HSTC) or a High-Speed
Mezzanine connector (HSMC) I/Os to three 40-pin expansion prototype connectors, which are compatible
with Altera DE2/DE1 expansion headers. Users can connect up to three Altera DE2/DE1 boards (or
associated daughter cards) onto a HSTC/HSMC-interfaced host board via a THDB-HTG board.
1-1Features
Figure 1.1 shows the photo of a THDB-HTG board. The impo rtant functions of the THDB-HTG are listed
below:
• Convert HSTC/HSMC-interfaced I/O to standard 40-pin expansion connectors.
• Allow users to connect Altera DE2/DE1 boards to a HSTC/HSMC-interfaced host board.
• Provide test points for signal measurement.
