J3 and J4 control which clock is routed to the A/D converters. See
J18 and J19 control which clock is routed to the D/A converters. See

Signal Name
3:
The Stratix II DSP development board can obtain a clock source from one
or more of the following sources:
■
■
The board can provide independent clocks from both the enhanced and
fast PLLs to the A/D converters, the D/A converters, and the other
components that require stable clock sources.
To implement this concept, the enhanced PLL5-dedicated pins drive the
A/D converters and associated functions, and the enhanced
PLL6-dedicated pins drive the D/A converters and associated functions.
