Note
3. Jitter is configuration dependent. Actual jitter is dependent on output frequencies, spread percentage, temperature, and output load. For more information,
refer to the application note, “Jitter in PLL Based Systems: Causes, Effects, and Solutions” available at http://www.cypress.com/clock/appnotes.html, or contact
your local Cypress Field Application Engineer.
