描述

What are the MB_FB_CLK and CLK_FB_MB pins used for in the XtremeDSP Spartan-3A DSP Starter Kit 1800A board?

These pins are listed in UG454 and the schematic of XtremeDSP Spartan-3A DSP Starter Kit 1800A.

解决方案

The MB_FB_CLK and CLK_FB_MB are not used by any software or IP and can be safely ignored. However, when building a memory interface to use with the DDR2 SDRAM, you will need to use the RST_DSQ_DIV pin.
