8 years agoDLL had delay elements (buffers) which shift the phase of the clock(as shown in the image attached). The application requires me to have a clock with 8 synchronized phase delays (i.e. 45,90,....,360). I am getting the desired frequency of the clock using PLL; however, to get these phase delays, I need to use a DLL.
Yes, it is possible to achieve the same using PLL by having a high-speed clock and then using digital logic and get the required number of slower phase delayed clocks. I'm trying to avoid this option as PLL output at that high frequency is not permissible on the DE4 board. It would be much easier if I could somehow get the buffer outputs instead.
