MIPI DSI to OpenLDI LVDS Display Interface Bridge

Please note that this site will be undergoing scheduled maintenance between 9 PM June 23, 2018 and 5 AM June 24, 2018 PDT. You may encounter some dropped connections and timeouts during this window. If you have problems, please return after this maintenance window.

We regret any inconvenience that this might cause.

Most mobile processors use industry standard interfaces such as MIPI DSI for interface connectivity. Larger consumer and industrial displays sometimes have a OpenLDI or LVDS interface that cannot be directly connected to a mobile application processor without a bridge. Many new applications want to leverage mobile innovations while utilizing larger displays with specific requirements and capabilities.

Lattice CrossLink is a programmable video interface bridging device capable of converting processors with MIPI DSI interfaces to OpenLDI at up to 6 Gbps per PHY. This bridge is available as free IP is available in Lattice Diamond for allowing easy configuration and setup.

Features
