The Clock Control

The Clock Control application sets the Si570 (X1) or Si571 (X3) programmable

oscillators to any frequency between 10 MHz and 810 MHz. The frequencies support

eight digits of precision to the right of the decimal point.

The Clock Control application runs as a stand-alone application. ClockControl.exe

resides in the <install

dir>\kits\cycloneVSX_5csxfc6df31_soc\examples\board_test_system directory.

To start the application, click Start > All Programs > Altera >

Cyclone V SoC Development Kit <version> > Clock Control.

f For more information about the Si570/Si571 and the Cyclone V development board’s

clocking circuitry and clock input pins, refer to the Cyclone V SoC Development Board

Reference Manual.
