The cable issue is why i like the SCSI III cabling

https://www.ebay.com/itm/Internal-SCSI-Ribbon-Cable-2-Drive-with-LVD-SE-Terminator-32-Inch/161643732466?hash=item25a2b79df2:g:HCkAAOSw34FVCz4Z

cut off the extra connector and terminator. 3' cable

Rerouter:
While I try and figure out how I am going to route the 1.27mm header, here is an 8 Channel pod using LMH7324's,

Not the smallest of things at 41x33mm, and the ribbon is most of that width, but the smaller header / ribbon version is on the todo list.

at a glance it should be possible to make this a 2 layer PCB, but I'm not up for that challenge just yet.

Rerouter:
And the 1.27mm header version, for a 0.635mm pitch ribbon. This requires a 0.6mm thick PCB to inline the header.

If you want to go more compact than this, it would need to use smaller components, At present I have been working to keep the 0603 minimum as set earlier.

Edit: missed a via, board files have been updated.

I think  you are hitting a good point. I understand where everybody wants to optimizethe design for their own use case. But going with 4 or 8 channel pods for the 'cheap' crowd, makes little sense, as it's far easier to just not get the LMH chips.

Even with the 4 channel chips the same goes :) Cheaper = don't solder the chips.

Do we really think that? I mean that Rigol is knowing what they are doing ;)


In any case, good progress is being made.

Rerouter:
I was working on 8 channel pods, mainly for ease of routing, they have a wrapped around pin order for a dual side loaded PCB, so if stuck to single side loaded PCB's, its easy to break into 2 logical units, but I am including all the design files. so people are free to edit them to there own requirements.
