PCIe-AE304bp – 4-Port Automotive Ethernet PCIe Card by Neousys

The PCIe-AE304bp from Neousys Technology is a purpose-built Automotive Ethernet PCIe card engineered for demanding in-vehicle test, validation, and edge computing environments. This wide-temperature fanless solution integrates four IEEE 802.3bw/bp compliant 100/1000BASE-T1 ports through robust H-MTD Z-code connectors, delivering native Automotive Ethernet connectivity directly to x86-based test platforms and edge computing systems. At the heart of the card are four Marvell 88Q2221 Automotive Ethernet PHYs, enabling reliable high-bandwidth communication with sensors critical to ADAS and autonomous driving development, including LiDARs and radars. The adoption of BASE-T1 technology addresses the automotive industry’s need for reduced cable weight, simplified wiring, and efficient high-speed networking over single twisted-pair cabling supporting up to 15 meters of unshielded twisted pair cable. Designed as a single-slot, half-length PCIe add-on card requiring a Gen2 x4 lane signal, the PCIe-AE304bp installs directly into standard host systems, eliminating the need for external media converters and associated cabling complexity. The locking automotive-grade connectors prevent vibration-related disconnection issues common with traditional RJ45 solutions. Software-configurable master/slave modes for both 100BASE-T1 and 1000BASE-T1 provide deployment flexibility, while IEEE 1588 Precise Time Protocol support enables sub-microsecond time synchronization with connected sensors. Operating reliably from minus 25 to 70 degrees Celsius without active cooling, the card meets CE and FCC Class A EMC standards. This solution serves engineers developing ADAS test benches, autonomous driving validation systems, and vehicle electronics testing platforms using standard computing hardware.
