Architecture Figure 2.2 The TDRB-H2S Back side – HSMC connector view The following components are provided on the THDB-H2S board : • HSMC expansion connector (J1) • Santa Cruz Headers(J3,J4,J5) • Mictor connector (J2) • SMA connector (J6) • 9-pin connector (J7) and RS232 Transceiver (U9) •...
This section describes the HSMC connector on the THDB-H2S board THDB-H2S board contains an Altera standard HSMC connector. All the other connector interfaces on the THDB-H2S 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 how to use the level translators and configuration headers on the THDB-H2S board The level translators of the THDB-H2S board convert the signal levels between the HSMC and Santa Cruz connectors according to the configurations of the headers (J8, J9). Figure 3.4 shows the block diagram of such function.
This section describes the Santa Cruz connector on the THDB-H2S board The THDB-H2S board comes with Santa Cruz connectors (J3, J4 and J5) to connect to a daughter board with Santa Cruz interface. Figure 3.5 shows the pin-outs of the Santa Cruz connector. Detailed pin mappings between J3, J4, and J5 to the HSMC connector is listed in Table 3.3, Table 3.4, and Table 3.5, respectively.

Cyclone III start board using Mictor interface is shown below: 1. Connecting the THDB-H2S board to the Cyclone III Start Board. 2. Removing the jumpers of JP1 and JP2 of the Cyclone III Start Board to connect the JTAG interface between Cyclone III FPGA and the THDB-H2S board.
This section describes the RS232 Transceiver and 9-Pin Connector on the THDB-H2S board The THDB-H2S is equipped with a RS232 transceiver (U9) and a 9-pin connector (J7) to provide RS232 serial I/O interface to the HSMC interface host board. The pin assignments of the RS232 interface are shown in Table3.7.
This section describes the I2C Serial EEPROM on the THDB-H2S board The THDB-H2S board provides an EEPROM (U8) 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 3.9.
