RGB to MIPI DSI Display Interface Bridge

Bridging Traditional Processors with Mobile Display Interfaces

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

Most mobile displays use industry standard interfaces such as MIPI DSI for interface connectivity. Traditional processors sometimes have a MIPI DPI or CMOS 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 CMOS interfaces at up to 300 MHz to MIPI DSI at up to 6 Gbps. This bridge is available as free IP in Lattice Diamond® for allowing easy configuration and setup.
