Hello expert,
My customer would like to design LMK1D1208 in their system but their received is CML topology. They would like to know if we have LMK1D1208 reference design for LVDS to CML?
I've already posted this document to customer but they would like to know if we have reference design especially for LMK1D1208.
Thanks a lot!
Best regards,
Ann Lien
Hello Ann Lien,
I found this article talking more about LVDS to CML conversion when DC-coupling. As shown in the picture below, you can use the SN64CML100 to convert an LVDS signal to a CML signal. Let me know if you have more questions about that device and I can redirect you to that team if you choose this route.
If you are AC coupling and don't want to use the added translator, I would suggest to do the following:
The R values are determined based on the biasing from the receiver required. Generally, they tend to be 50 ohm.
Also, this articles may help you when dealing between terminations and explains more about their architectures.
Hope this helps!
Good luck,
Andrea
