Hi @quincyq2003

 

You can follow the same procedure which is provided in UG571 to cascade four delay elements.

 

Note: Make sure you are not crossing the byte boundary while cascading delay elements.

 

Thanks,

Vinay

Hi @vuppala 

I cannot see how can even number (four) of delay element can be used. If I continue the pattern located in the IDELAYE3 chapter of the UG571, I can cascade only odd number ofdelay elements.

Is it realy possible to connect four delay elements? I think we can connect five elements and we can set zero delay one of them.
