The AD-GMSL2ETH-SL is an edge compute platform enabling low-latency data transfer from eight Gigabit Multimedia Serial Link™ (GMSL) interfaces on to a 10 Gb Ethernet link. The target applications include autonomous robots and vehicles where machine vision and real-time sensor fusion is critical.

The system includes two MAX96724 Quad Tunneling GMSL2/1 to CSI-2 Deserializers, enabling connectivity to eight GMSL cameras. The video data from the cameras is transferred from the MAX96724 deserializers via MIPI CSI2 interfaces to an AMD KV26 System on Module which implements the logic to aggregate the video data from all the GMSL cameras into a 10 Gb Ethernet link, so that it can be sent to a central processing unit.

The IEEE 1588 Precision Time Protocol (PTP) with hardware timestamping is supported, enabling accurate synchronization with host systems and other edge devices. The AD9545 Quad Input, 10-Output, Dual DPLL/IEEE 1588, 1 pps Synchronizer and Jitter Cleaner is used to generate the required clocks for the 10 Gb Ethernet interface and the PTP logic.

A software networking stack can be used to realize the communication over the 10 Gb Ethernet link. Since the system runs Linux tools like gstreamer can be used to send the video data to a host and remote connection into the system is possible via ssh. The software network stack has limitations in terms of the maximum achievable transfer rate, and for this reason there is also the option to have an FPGA accelerated UDP or TCP implementation with Real Time Transfer (RTP) protocol for data packetization, which can get up to the maximum achievable data rate on the 10 Gb ethernet interface.

Accurate camera triggering control is achieved through dedicated FPGA logic, with configurable frequency and phase as well as selecting the trigger source between the internal logic and external signals.

Sixteen (16) general purpose I/O pins are available with software configurable functionality, operating at 3.3 V voltage level. A RS232 dedicated interface can be used to connect UART peripherals such as GNSS devices.

The design is accompanied by an open-source software stack and FPGA design, and reference applications, enabling custom software development to start from a proven implementation.

The AD-GMSL522-SL is a GMSL-enabled NVIDIA Jetson Xavier™ NX-based carrier board and software solution that allows for simple camera to display conversion. This solution creates a scalable, user friendly, GMSL platform for receiving and transmitting data over a gigabit multimedia serial link (GMSL). The platform enables demonstrations and ecosystem development by serving as a hardware platform for software development.

The AD-GMSL522-SL supports two forms of camera input -- either straight CSI data coming through a SAMTEC connector, or via camera modules using GMSL2 or GMSL1 technology to connect to the on-board MAX96724 via COAX connectors. GMSL evaluation kits or any camera utilizing the standard 15- or 22-pin Raspberry Pi connector can be connected here using the AD-GMSLCAMRPI-SL adapter board.

The AD-GMSL522-SL package includes software tools to enable customers in their 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 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.

There are two system options available for purchase: the AD-GMSL522-SL which is the base carrier board and does not include the NVIDIA SoM, and the AD-GMSL522-SOM-SL which is the carrier board including the NVIDIA Jetson Xavier™ NX SoM.
