RGB to MIPI DSI Display Interface Bridge

Bridging Traditional Processors with Mobile Display Interfaces

Take our survey!Help us make this website even better by taking an anonymous eight question survey! Click here to start.

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.
