Introduction
1
The THDB-H2G board is designed to fan out the 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 HSMC-interfaced host
board via the THDB-H2G board.
Figure 1.1 shows the photo of the THDB-H2G board. The important functions of the THDB-H2G are listed
below:
Converts HSMC interface I/O to standard 40-pi n expansion connectors.
•
• Allows users to connect Altera DE2/DE1 board
• Provides test points for signal measurement.
