The Clock Control
The Clock Control application sets the Si570 programmable oscillator to any
frequency between 10 MHz and 945 MHz and select frequencies to 1400 MHz. The
oscillator drives a 2-to-4 buffer that drives a copy of the clock to all four edges of the
FPGA.
The Clock Control application runs as a stand-alone application. ClockControl.exe
resides in the
\kits\stratixVGX_5sgxea7nf40_si\examples\board_test_system
directory.
On Windows, click Start > All Programs > Altera > Transceiver Signal Integrity

Signal Integrity Development Kit Stratix V GX Reference Manual .
The Clock Control communicates with the MAX II device on the board through the
JTAG bus. The Si570 programmable oscillator is connected to the MAX II device
through a 2-wire serial bus.
Figure 6–10 shows the Clock Control.
The following sections describe the Clock Control controls.
