Five- Ports AVB and TSN Automotive Ethernet Switch

SJA1105TEL

Roll over image to zoom in

The SJA1105TEL Ethernet switch offers a flexible solution for implementing modular and cost-optimized Electronic Control Units (ECUs) using Ethernet as the backbone for control applications.

  • The SJA1105TEL extends the SJA1105EL features with a set of Time-Sensitive Networking (IEEE TSN) standards that enable the deterministic partitioning of the network’s bandwidth between critical/control and non-critical/best-effort traffic.
  • Besides implementing control-application over Ethernet, these features are also ideal for the simple integration of modular Advanced Driving Assistance Systems. For example, a single rear-view camera scaling up to full surround view application.
