Figure 1 AD-GMSL522-SL GMSL Board

The AD-GMSL522-SL is a Gigabit Multimedia Serial Link(GMSL)-enabled NVIDIA Jetson Xavier NX-based hardware and software solution that allows for prototyping with GMSL technology. This solution creates a scalable, user friendly, GMSL platform for receiving and transmitting data over GMSL. It supports two forms of camera input – either straight CSI data coming through a SAMTEC connector from a GMSL evaluation kit, or via camera modules using GMSL2 or GMSL1 technology to connect to the on-board MAX96724 via COAX connectors. The package also includes software tools to enable development of GMSL applications. Among these tools are modified L4T kernels that support certain camera modules and documentation that allows any user to update these kernels for their specific hardware needs. The design also incorporates the MAX96724GTN/VY+ Quad tunneling GMSL2/1 to CSI-2 deserializer and MAX96717GTJ/VY+ CSI-2 to GMSL2 serializer and provides a reliable platform to evaluate high-bandwidth GMSL.

Features

  • Hardware solution that bridges the gap between GMSL2 technology and the NVIDIA Jetson

  • On-board MAX96724 that allows 4x GMSL2/1 camera inputs that allows for camera module bring-up, debug, and video streaming

  • On-board MAX96717 that can be used for camera emulation and head-unit debug

  • Enables development of GMSL applications with NVIDIA Jetson SoC

  • SAMTEC connector that allows connection of any GMSL DPHY EV Kit to the NVIDIA Jetson

  • Additional inputs: USB, Ethernet, PCIe, and microSD card

Applications

  • ADAS Camera Solutions

  • Sensor Fusion ECU

  • Driver and Occupant Monitoring

  • In-cabin Infotainment
