Suggestion for a cable

Hello,

if you need 7 differential signals and 10 normal signals, you should have some ground lines too. A shield may be useful.

There are companies that make custom cables.

Shouldn't be too hard.

You will almost certainly need a custom PCB to connect to the HSMC connector, both sides are designed for PCB mounting.

Any suggestion? I've seen samtec, but i'm looking for cheaper company

If the cable is to be placed in a pathway it needs to be armored to protect it. If it is an interconnect and its path is protected from abuse you can go softer.

You could use Ethernet cables (2 of them) to make the LVDS runs.

Final length also matters and you did not mention that either.

Buy a spool of Silver Plated Copper 20 gauge Teflon wire (SPC TFE)and make the ten straight runs and twist up 7 pairs for your differential runs, put some lacing cord ties along the length, and put it all in a big piece of heat shrink or braided jacket. Way cheaper than looking for some near match pre-done cable. Especially the lost personal time looking for it.

Can you use twisted pair for the LVDS signal lines? Have you looked through the Belden and other wire catalogs. They make lots of different cables with multiply twisted pairs.

Belden does have a 24 (12 twisted pair) cable. And if you look at most LVDS LCD's you see they use a cable by Copartner.
