AC coupled and 50 Ohm input of LTC5967 buffer. Sigi gave you the right answer.

It should remember the layouts and home location – they are independent. So select a layout, make changes, switch etc.

When changing layouts 1 thru 5 shows the same layout and the home indicator show correctly when choosing the default layout but choosing layout 1 to 5 places the home location at Simon’s place.

Tried it, looks great. But some issues:

  • It sucks 90% CPU when I go to the Great-Circle map.
  • Entering my home-position was tricky due to those Common-Control (?) digit-field widgets.

Re: SDRC and Pluto with external reference

Siegfried Jackstien
 

joanne you show that you do not know the rev c/d :-)

it is for sure ac coupled ... and "around" 50 ohms

i do not know the input impedance of the buffer chip but the input line is with a 50 ohms (49.9) resistor and a series cap

(sidenote to karen ... internal is an xo not a tcxo ... otherwise the drift would be way lower)

another hint (also for all other readers) ... if you want to replace the xo to a tcxo in new revision you have to rewire the switching transistor Q2 from enable pin of the xo ... to the enable pin of the power regulator chip U12 ... 3 cuts with a sharpie and 2 additional wires are needed then

cut the connectio on U12 pin 4 (next to the via), cut the connection between enable of the clock and R67 and cut the connection between R101 and 1P8V_CLK

connect R101 to PG1V3 and connect R67 to pin 4 of U12

now the transistor pulls enable pn of U12 to ground and the (now changed) clock does not get power anymore when you select external clock to be active
