Hi, Would you pls. take a look at the attached three eyediagrams?
Eyediagram1 is a normal eyediagram. But eyediagram2 and diagram3 shows the crosspoint of the eyediangram shifted from midpoint seriously, especially for the eyedianrgram3, the crosspoint even disappeared. I checked my design spec, for the rise/fall time it is OK. And for the another spec of PWD(pulse waveform distortion), although the crosspoint of the eyediangram2&3 shifted seriously, they also meet the PWD spec because of the sharp rise/fall edge.
I wonder if the eyediagram2&3 is indeed OK for the system even they meet the design spec?
Thanks in advance Dandelion
