RS422 to LVDS

I want to convert RS422 signals to LVDS, but I don't know the method or IC.

    Hi,

    One method would be to convert the RS-422 signal to TTL using a RS-422 receiver, then drive an LVDS driver with the TTL signal. The inverse can be done to convert LVDS to RS-422. You would need to be sure the TTL voltages between the devices are comparable (LVDS often has low input voltage requirements). Also consider the data rate being handle by both transceivers as well as the added propagation delay of your system. 

    To find specific ICs for your implementation, you can search transceivers by protocol on ti.com from the products -> interface page.

    Let me know if you have specific questions about your implementation or more suggestions that may work for your system.

    Regards,
