1 Input to 2 Output MIPI CSI-2 Camera Splitter Bridge

Expanding Camera Applications by Connecting Two Cameras From a Single Application Processor Port

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

Mobile cameras and processors are being used for new and exciting applications. A 1:2 MIPI CSI-2 to MIPI CSI-2 splitter is sometimes needed to connect the same camera to two different processors. An example of this is when one processor is used for analytics or live display and the other processor is used for image processing and storage.

Lattice CrossLink™ is a programmable video interface bridging device capable of solving these problems and providing multiple MIPI CSI-2 interfaces at up to 6 Gbps per PHY. This bridge is available as free IP in Lattice Diamond® for allowing easy configuration and setup.


  • Supports MIPI CSI-2 up to 6 Gbps per MIPI D-PHY: 1, 2 or 4 data lanes
  • Provides one or two MIPI CSI-2 outputs: MIPI CSI-2 data replicated to each output port
  • Supports all MIPI CSI-2 data types: RAW, YUV, RGB, User Defined
  • Compliance with MIPI D-PHY Specification v1.1
  • Compliance with CSI-2 Specification v1.1
