About the LVDS output swing

user1333423

I choose a device with 2.5V LVDS ouput ，and the output voltage swing is 250mV~450mV.

But the sink device is a 1.8V LVDS，and the input voltage require is 130mV~300mV.

How can I connect these two devices?

Hello,

You can reference this blog: e2e.ti.com/.../get-connected-interfacing-between-lvpecl-vml-cml-lvds-and-sub-lvds-levels

I believe Figure 4 (LVDS to Sub-LVDS Termination Scheme) is what you are looking for.
