Ultrascale ISERDESE3 with edge timed DDR data

Jump to solution

Can ISERDESE3 (Ultrascale Kintex) be presented with edge timed DDR data?

(or is it necessary to either (a) phase shift the DDR clock by 90 degrees in an MMCM/PLL, or (b) add an IDELAYE3 in time mode?)

There are setup and hold time for the ISERDESE3 that needs to be met. 

There is a clock alignment that is done in UltraScale automatically when you include the IDELAY : https://www.xilinx.com/support/answers/64743.html
