Introduction Introduction 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.
Architecture Architecture This chapter describes the architecture of the THDB-H2G board including block diagram and components. Layout and Componets The picture of the TDRB-H2G is shown in Figure 2.1 and Figure 2.2. It depicts the layout of the board and indicates the locations of the connectors and key components.

Architecture HSMC Connector(J1) Figure 2.2 The TDRB-H2G board back side – HSMC connector view The following components are provided on the THDB-H2G board : • HSMC expansion connector (J1) • Expansion prototype connectors (JP1,JP2,JP3) • I2C serial EEPROM (U2)
This section describes the HSMC connector on the THDB-H2G board THDB-H2G board contains an Altera standard HSMC connector. All the other interfaces on the THDB-H2G board are connected to the HSMC connector. Figure 3.1, Figure 3.2, and Figure 3.3 show the pin-outs of the HSMC connector.
This section describes the expansion prototype connectors on the THDB-H2G board. The THDB-H2G board has three expansion prototype connectors (JP1, JP2, and JP3) connected to the HSMC connector directly. Each of the connectors has 36 prototyping I/Os and 3.3/5 volts power supply from the HSMC interface and on-board regulator.

This section describes the I2C Serial EEPROM on the THDB-H2G board The THDB-H2G board provides a Microchip 24LC000 EEPROM (U2) which can be configured by the I2C interface. The size of the EEPROM is 128-bit that can store the board information or user’s data. The detailed pin description between EEPROM and HSMC connector is listed in the Table 3.4.
This section describes how to use the THDB-H2G board with a Cyclone III Starter Board. Figure 4.1 illustrates how the THDB-H2G board is connected to the Cyclone III starter board. Users need to pay extra attention to the following two points: Observe the orientation of the HSMC connector when connecting the THDB-H2G to the Cyclone III Starter Board.
