interface stratixIV with an external ultrafast comparator

Hi everybody :) we need to interface ultrafast comparator- ADCMP572 - of analog device to a stratix4 device to perform one bit conversion. we expect that the comparator will ouput very short...

Probably Higher...

But there is a dynamic(real time) reconfiguration into the PLL-with a 78ps resolution. we can eventually use this option to "achieve the phased sampling".

Mean feed the latch input from a pll output only by using the I/O GT ? the jitter will be always inferior to 100ps ??
