OpenLDI LVDS to MIPI DSI Display Interface Bridge

Bridging Traditional Processors with Mobile Display Interfaces

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 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.

Features

  • Supports MIPI DSI Input at up to 12 Gbps
  • Supports OpenLDI LVDS at up to 9.6 Gbps
  • Supports single or dual link LVDS to single or dual MIPI DSI outputs
  • Supports DSI compatible video formats (RGB) :
    • RGB888
    • RGB666
    • RGB888
  • Compliance with MIPI D-PHY Specification v1.1
  • Compliance with DSI Specification v1.1
