Frequency button and press Enter or click the button (see the following figure). After the

Set CLK-101 Si5368 Frequency
There are two buttons in the Set tab that can be used to program the Si5368 clock source: Set
Si5368 Frequency (Auto Select) and Set Si5368 Frequency (Free Running). The free-running
option uses the onboard XA-XB crystal as the active clock routed to the Si5368 internal PLL. The
auto select option uses one of the recovery clocks routed to the SuperClock-2 Module interface
as the active clock. Enter the desired Si5368 frequency in MHz in the field next to either the
auto select or free-running buttons and press Enter or click the related button (see the following
figure). After the frequency is set, the Logging pane shows no errors and prints Finished.
