[time-nuts] Simple GPSDO Multiple Outputs - buffered line driver options?

[Bob kb8tq]

Hi

What are you driving? 

Most “normal” gear is pretty happy with a fairly wide range of input levels. Obviously things
like termination and long lengths of coax can get into the act. For 4 outputs, a passive splitter
with 6 db of loss should do just fine. You have only taken the output voltage down by 2:1 ….

Just for reference:

Calls out a 200 mv to 10V RMS input level as acceptable For a variety of reasons, 10V RMS
is a really bad idea (cross talk ….). Lower is better in this case.
