occheung 2d0a866274 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.

occheung 5c44a65d33 5568: init
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.

occheung 3ed6a7ccbe 2118-2128: fix data rate spec
Quoted from the isolator datasheet: "Data rates up to 150 Mbps are supported."
Saying the maximum data rate is at least 150 Mbps is not very accurate.

occheung d622423675 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.

occheung 1b8beee45d 2118-2128: add max data rate spec
Base on the isolator datasheet, where it stated that "Data rates up to 150 Mbps are supported".
The electrical specific of the datasheet stated the spec differently.

The only signal that enters the ADC through the repeaters is the SPI clock.
It is only a state/time reference, no meaning info goes through this path.
