The CM SerDes of Technica Engineering is a logging device for the GMSL 2/3 technology. It is used to capture and timestamp SerDes communication, which is needed to log the communication data of modern camera systems (sensors and / or ECUs).


With the Capture Module SerDes, you can capture up to 4x GMSL2/3 sensor data stream point-to-point connections without influencing the network itself. Sensor data (GMSL forward link) is forwarded from the sensor (connected to the CM deserializer port) to an ECU (connected to the CM serializer port). At the same time, the data is being captured and sent to a logging port packetized in Ethernet frames using the PLP/TECMP protocol. Control data (I2C and GPIO) transmitted using the GMSL reverse link is also forwarded between the sensor and the ECU while it is being captured by the CM.


To be able to log ata with a minimal impact on the tested system, the Capture Module is placed in the middle of the communication line that is observed. This way, timestamping of the data sent that is sent over the line is enabled.


Our Capture Module SerDes can be used to log up to 4 channels of GMSL 2/3 data, hence it has 8 ports (4x incoming traffic, 4x outgoing traffic). The device has two MATE-AX Quad Fakra connectors for the GMSL2/3 incoming and outgoing traffic lines. For sending the captured traffic, it has 4 SFP+ slots. Via these SFP+ ports, the logged data can be transferred to a data logger or PC.


Additionally, the Capture Module Serdes GMSL2/3 contains a power connector, two Gigabit Standard Ethernet ports for configuration / time sync, and a rotary switch to configure the device IP. When the Capture Module Serdes GMSL2/3 is connected to a PC via the configuration port and a LAN cable, you can configure the device via an easy-to-use HTML configuration website.


Each message captured from the in-vehicle network (Automotive Ethernet, CAN, LIN, SerDes, …) is encapsulated in a standard transport layer frame. This requires embedding in a standard Ethernet frame according to IEEE 802.3. Data from non-Ethernet communication systems, as well as Ethernet-based systems, are transported in Ethernet frames and identified unambiguously using the protocol PLP/TECMP.


Our CM SerDes supports 802.1AS to enable time synchronization in applications with multiple communication technologies (SERDES, CAN, LIN, Automotive Ethernet, …) logged by our Capture Modules. Further, the PLP and TECMP protocols are supported to provide synchronized logfiles including important meta data, ASAM CMP will also be supported as well.
