Deterministic Ethernet Switch for Application Development and Evaluation of AVB and TSN

We are announcing the launch of the Deterministic Ethernet switch Hermes for application development and evaluation of in-vehicle network architectures in the field of automotive and heavy machinery. With this intelligent device, our customers can now evaluate multiple technical standards supported by the NXP SJA1105T chip, including AVB, TSN and Time-Triggered Ethernet. The switch also integrates a powerful CPU running AUTOSAR 4.2.1 and provides digital and analog I/Os plus CAN, FlexRay and Ethernet interfaces.

The DESwitch Hermes 3/1 BRR makes the development and evaluation of AVB and TSN possible in a versatile form factor. The NXP SJA1105T chip enables networks with standard Ethernet for best effort traffic, Quality of Service (QoS) for using VLANs and priorities, Audio-Video Bridging (AVB) for clock synchronization and traffic shaping, Time-Sensitive Networking (TSN) for time-aware shaping and Time-Triggered Ethernet for time-triggered communication and fault-tolerant clock synchronization. Combined with its integrated control functionality, the Hermes switch will enable a wide range of in-vehicle projects for diagnostics, control applications, infotainment and advanced driver assistance systems (ADAS).

NXP has previously licensed our Ethernet Switch IP and used it to develop the first Ethernet switch chip SJA1105T. “The Hermes Deterministic Ethernet switch from TTTech serves as a platform for evaluating the functionality of our SJA1105T Ethernet switch IC, making this another stepping stone within our valuable cooperation,“ says Günter Sporer, Segment Director Ethernet at NXP Semiconductors.
