2238: add spec on max voltage with term
...
Updates #35 .
Same termination structure as bnc/sma-ttl card.
Technically the max allowable voltage with termination is a bit higher than 5V.
But it seems that it will still exceed the termination resistor rating limit at 5.5V.
The only method of acquiring V_ds & other parameters is by eye-balling the I-V curve of the MOSFET, which is not precise.
So the calculation assumes V_ds=0, just to be conservative.

There aren't any electrical specs, as suggested by the lack of electronic components.
There is a colored version of the connection diagram, but I think the B&W one actually looks better.

4456: remove mention to cpld cfg on rf_sw
...
As communication to ALmazny mezzanine does not use bitbang anymore, there is very little value for routing LVDS signal.
Also, MUXOUT readout from ADF5356 has an easily understandable API available.
So there should not be any reasons to use EEM[4:8] for anything other than controlling RF switches.
