Appendix 1 Clock generator programming

The XtremeDSP Spartan-3A DSP Development Board features an Integrated Device Technology (IDT) 3.3-V
EEPROM programmable clock generator that allows you to program the board's clocks. This appendix explains
how to use the IDT software to generate a combination of clock frequencies and implement them onto the
XtremeDSP Spartan-3A DSP Development Board with a Xilinx download cable and JTAG flying wires.

Installing the clock generator software

1. Visit the IDT Web site
2. To download the ZIP file of the program, in the Related Documents group at the bottom of the page, click
Programming Software.
3. Unzip and install the software.
4. At some point, you may be prompted to install the Java Runtime Environment. Install it.
5. Follow the instructions on your screen to complete installation.

Generating an SVF file

When the IDT software is installed, use it to create an SVF file to program the clock chip of the XtremeDSP
Spartan-3A DSP Development Board.
To start the IDT program
1. On the Windows Start menu, point to IDT Programmable Clock Devices, and then click IDT
Programmable Clock.
2. When the program starts, click 5V9885.
