A.3. Clock Circuits
All clocks are supplied by two on-board low-jitter programmable clock generator circuits. The following figure depicts the clock connection to the Intel® Stratix® 10 DX FPGA:
The default clock frequencies are as listed in the table. All the clock frequencies can be changed by using the Clock GUI.
