The designer's choices also will help control costs and save space and weight. Modular and scalable MATEnet connectors developed by TE Connectivity for automotive Ethernet, for example, can also be used in heavy-duty vehicles for applications requiring mid- to large-size data volumes and low latencies, such as onboard diagnostics (V2X technologies), telematics, dashboard infotainment, ADAS, and more. The connectors can transmit data at 100Mbps to 1Gbps (per IEEE 100BASE- T1/1000BASE-T1) and can be used with unshielded or shielded twisted-pair cables. On-chassis components require more than just ruggedness. They must demonstrate mechanical reliability, be serviceable, withstand extreme temperatures and operate efficiently with longer channel lengths. When dealing with higher frequencies, cable/connector quality and design can significantly impact channel performance, which affects application performance. Especially for on-chassis components, engineers need to opt for cables and connectors specifically designed for high-speed data transmission in harsh environments. "When trying to meet mechanical resilience needs, some engineers may instinctively think to add a larger, more robust housing, but thicker walls may negatively impact electrical performance," says Mark Brubaker, Data Connectivity Product Manager, TE Connectivity. "It's important to look at what historically has worked, but also to take a further step to understand this new generation of electrical needs for transmitting high-speed data and test how connections will perform given the higher frequencies involved." Conclusion Product choice and placement cannot be an afterthought when designing advanced and automated functionality that requires high-speed data transmission. When adding Ethernet to heavy- duty vehicle architectures, designers must think about and plan for the complexities involved much earlier and deeper than before to successfully balance reliability and mechanical resilience with electrical requirements for high-speed data and longer channel lengths, as well as serviceability needs. ■
