3.4  Clock Sources 

The Clock Generation section of the Virtex-4 MB board provides all the necessary clocks for a 
MicroBlaze processor, the I/O devices located on the board, as well as the DDR SDRAM 
memory. In general, the clock sources on the board are grouped into two categories; differential 
and single-ended clock sources. The differential clock sources are primarily used by the LVDS 
interface, while the single-ended clock sources are used by the processor section. 
 
An on-board 100MHz oscillator provides the system clock input to the processor section. This 
100Mhz clock will be used by the Virtex-4 Digital Clock Managers (DCMs) to generate various 
processor clocks. In addition to the above clock inputs, a socket is provided on the board that can
