[time-nuts] LTC6957 Low Phase Noise Buffer/Driver

[Bob Camp]

Hi

The "high gain" stuff was in relation to the front end that's optimized to
convert sine waves to logic levels. It sounded like they are doing some sort
of saturated stage and then converting it's output to ECL.

I thought the whole point of fast ECL logic was that it never saturated. 
  Of course these days, one might have very fast saturating logic that 
happens to have ECL logic levels and run off that ever so convenient 
-5.2 V power supply.
