Linux Driver for the LT6911UXC HDMI to MIPI CSI-2 Converter

The ZHAW Institute of Embedded Systems (InES), High Performance Multimedia Group, developed a 4k video for Linux driver for the Lontium LT6911UXC HDMI to MIPI CSI-2 converter IC.
The driver was written for NVIDIA Jetson Processors and enables the following features of the LT6911UXC

  • Supports 4k HDMI 2.0 to MIPI CSI-2, requiring only one CSI port
  • Up to 4k resolution
  • Only 4 CSI lanes (one port) are required to receive 4k@30fps
  • Converts 4:2:2 YcBCr to CSI-2 YUV streams 1)
  • Converts RGB to RGB CSI-2 streams 1)

A driver for the advanced LT6911GX with HDMI 2.1 support and 4k@60fps on a single CSI-2 port is in the pipeline at InES-HPMM group.

1) If RGB or YUV streams are accepted depends on the corresponding LT6911UXC firmware provided by Lontium. Contact Lontium for the firmware.

  1. Hi there, I have stumbled upon your page whilst looking for solutions to integrate a thermal camera with the Jetson Xavier AGX. As the thermal cam has an hdmi output, do you think the Lontium hdmi to mipi bridge, along with the driver you have written, will integrate the cam and AGX well?
