Other Trends

Consolidation of Switch and PHY Functions

Suppliers are accelerating integration efforts to combine Ethernet switching, Time‑Sensitive Networking (TSN) scheduling, and PHY capabilities into unified silicon platforms. This consolidation lowers part count, reduces power draw, and improves thermal performancekey considerations for electric vehicle power budgets. Recent product roadmaps highlight support for 100 Mbps, 1 Gbps, and emerging 2.5 Gbps Ethernet speeds within a single package, allowing OEMs to scale bandwidth without redesigning harnesses. The trend also fosters software‑defined networking approaches, where firmware updates can reallocate bandwidth on‑the‑fly to match dynamic load profiles.

Shift Toward Multi‑Gigabit Ethernet Standards

Beyond 1 Gbps Ethernet, the industry is gravitating toward multi‑gigabit standards such as 2.5 Gbps and 5 Gbps to accommodate high‑resolution cameras, lidar, and over‑the‑air updates. Integrated TSN switch chips are being engineered to support these higher rates while preserving deterministic timing guarantees. Early adopters report up to a 30 percent reduction in end‑to‑end latency when migrating from separate PHY and switch solutions to fully integrated devices. As vehicle platforms evolve toward software‑centric architectures, the ability to deliver reliable, high‑throughput connectivity on a single silicon solution becomes a decisive competitive advantage.
