PCIe Technology for Long and Short Reach in Automotive Applications

Automotive infrastructures are evolving towards a distributed architecture with multiple safety-critical electronic control units (ECUs) close to the sensors that transmit live, data from all points of a car to other ECUs to make real-time decisions. As ECUs become more interconnected, a reliable method is needed for inter-ECU long-reach connections, especially for life-critical applications requiring high resolution, large amounts of data and split-second decisions. PCIe technology over cable is a viable, low latency, long-reach interface for in-vehicle ECU connectivity. For short reach applications within the ECU, retimers, redrivers and crosspoint/multiplexer (MUX) devices can increase link margin and further enhance PCB routing flexibility for system redundancy and fan-out distribution.
This webinar introduces the benefits of PCIe technology-based connectivity in automotive inter-ECU networks. Presenters will discuss the challenges of long-reach connectivity, and the implication of PCIe technology implementation in automotive applications. Attendees will also learn the protocol advantages of PCIe architecture, the realization of native PCIe technology over long-reach cables and signal conditioning considerations.
