STM32WB55 Comparator max speed

I have a board NUCLEO-WB55 and I'm testing some examples.

I'd like acquire a sine wave about 14 MHz and convert to square wave with internal comparator.

I can't find enough informations on datasheet if it's fast to acquire this signal.

Thank you for suggestions

for 14 MHz you have 36ns per hi or lo, so 55..80ns is slow, just try it. maybe working - because chip should be always faster than written in ds.

what information is missing here ?
