Description
The Neousys PCIe-AE304bp is a rugged, wide-temperature PCIe expansion card that provides four native 100/1000BASE-T1 Automotive Ethernet ports for x86-based systems. Designed for ADAS development, autonomous driving validation, in-vehicle testing, and edge AI applications, it enables direct connectivity to high-bandwidth sensors such as LiDAR, radar, cameras, and ECUs. Featuring four Marvell 88Q2221 Automotive Ethernet PHYs, the card supports software-configurable 100Mbps or 1Gbps operation with selectable master/slave modes. Its half-length PCIe Gen2 x4 design installs directly into standard systems without requiring external media converters, while locking automotive connectors ensure reliable connections in high-vibration environments. Support for IEEE 1588 Precision Time Protocol (PTP) provides sub-microsecond time synchronisation for accurate sensor fusion and data acquisition.
By delivering four native BASE-T1 interfaces from a single PCIe slot, the PCIe-AE304bp reduces system complexity, cabling, and latency, making it an ideal solution for Automotive Ethernet development, vehicle electronics testing, and next-generation edge computing platforms.
