Alex,

My initial plan is to provide only 10MHz and 1pps outputs from GIBRALTAR.
They would be 50 Ohm outputs on SMA connectors. The number of such outputs
is TBD.

I have much of the initial design done. I have been delayed by a trip to San
Diego for the AMSAT Digital Transponder Design Meeting and the Naval
Academy's MidStar-1 satellite that I am also working on.

I'll have a low-level design out on CASMIR tomorrow. It's a KISS design
based off of JANUS with a few cheeky twists. 
I had been trying for something elegant, but the idea didn't pan out. Oh
well.

Still looking for the answer on LO distribution from GIBRALTAR. I'm not
putting a LO on CASMIR, so I need the LO from GIBRALTAR (or elsewhere). 
Will LO distribution be differential or single ended LVDS? 

Alex, N3NP
