ADCMP572 can drive the load of 256pF?

Question

Accepted Answer

Q 
 Will ADCMP572 can drive the load of 256pF? If not , which comparator can drive 
 
 that capacitance? 
 
 A 
 The comparator is built to drive 50 Ohm complex loads but doesn’t specify 
 
 capacitive load capability.

Basically, it will work, just the question is: what is the customer’s 
 
 expectation on rise and fall time (slew rates) with this huge capacitive load? 
 
 Also depending on the input frequency, the output may start to oscillate.

Even if not liked by the customers, my suggestion is to use something like the 
 
 ICS83115 by IDT as fan out buffer in between, here’s the link:

or the 853S024 also by IDT:

 fanout-buffers/853s024-low-skew1-24differential-33v25v-lvpecl-fanout-buffer.

and think about the architecture once again.
