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...

I think that making use of the latch function of the comparator is the only way to make it work.

Why, the input bitstream will be latched by the receiver as well. A single bit can be either '0' or '1', you don't get more information by latching it externally before. Furthermore, not latching the signal will increase the available time resolution up to the maximum bit rate of the Statix IV device. But implementation details depend of course on the exact design purpose, that hasn't been said yet.
