In a complex system, it is common to do a frequency offset during the manufacturing process to understand the system clock timing margin. This would traditionally be done using two crystal oscillators on a single board. The two oscillators are electronically selected by a third component during the margin test. Using the PureEdge solution, it is possible to use a dual frequency device to do the margining test. The frequency selection is controlled via software. By using fewer components, the test time is minimized, system reliability is improved and the total cost of the system is reduced.
