Virtex/-E - Will the CLKDLL keep its lock if the input clock duty cycle changes but the period remains the same?

描述

Will the CLKDLL keep its lock if the input clock duty cycle changes but the period remains the same?

解决方案

Yes, the CLKDLL will stay locked in this circumstance. The DLL looks only at the positive edge of the clock, so the duty cycle of the clock is not a concern. As long as the period does not change, it will stay locked.
