OpenLDI LVDS to MIPI DSI Display Interface Bridge

Bridging Traditional Processors with Mobile Display Interfaces

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

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