• Use the frequency select switch (SW2) shown above
to choose the desired prole
• The proles are pre-loaded in the internal ash of
the clock device
• The frequency congurations for each prole are as
shown in Table 1
• Download and install the latest kit software from
www.cypress.com/go/CY3679
• Connect the kit to your computer using the USB
cable provided
• LED1 and LED2 are turned ON
• Connect OUT11 or any output you wish to evaluate
to the oscilloscope using an SMA cable
