CAN XL: Bridging 20Mbps Pure Fieldbuses with Ethernet Tunneling

Deploying 2048-byte frames and 20Mbps data rates to unify legacy automotive bus topologies with IP-based service architectures.

CAN SIC XL Transceivers: Eliminating Ringing on Star Topologies

High-speed data phases on legacy twisted-pair cables create destructive reflection ringing at branch splices. Standard CAN transceivers required linear bus topologies without long stubs. CAN SIC XL silicon actively drives the bus differential voltage back to recessive levels during transitions, dampening ringing and allowing complex star topologies at 20Mbps.

Native SOME/IP Message Transport Over CAN XL MTU

SOME/IP (Scalable service-Oriented MiddlewarE over IP) headers alone consume 16 bytes, making transport over CAN (8 bytes) or CAN-FD (64 bytes) inefficient due to constant fragmentation (SOME/IP-TP). With CAN XL's 2048-byte MTU, entire SOME/IP service invocations and payloads fit into a single frame, bridging seamlessly into Ethernet gateways without CPU-heavy reassembly buffers.
