MIPI DSI to OpenLDI LVDS Display Interface Bridge

Important: For new designs, Lattice recommends using the following modular IP blocks to implement this function:

The following Reference Design provides an integration example using these modular IP blocks

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.
