FEATURES
Description
4-Port Automotive Ethernet PCIe Card for ADAS, Autonomous Driving and Edge Computing
The PCIe-AE304bp from BRESSNER Technology is a high-performance Automotive Ethernet PCI Express card engineered for in-vehicle testing, ADAS validation, autonomous driving development, and industrial edge computing applications. Designed to provide native 100/1000BASE-T1 connectivity, the card enables direct communication between x86-based computing platforms and high-bandwidth automotive sensors such as LiDARs, radars, and intelligent ECUs without requiring external media converters.
Featuring four IEEE 802.3bw/bp Automotive Ethernet ports via robust H-MTD connectors, the PCIe-AE304bp supports software-configurable 100BASE-T1 and 1000BASE-T1 communication with flexible master/slave operation. Four integrated Marvell 88Q2221 PHY transceivers ensure reliable, high-speed data transmission while reducing cabling complexity through single twisted-pair Ethernet technology.
For precise sensor synchronization, the card supports hardware IEEE 1588 PTP v1/v2 and IEEE 802.1AS timestamping. As a result, it provides sub-microsecond timing accuracy for multi-sensor fusion and autonomous vehicle development.
Moreover, the half-length, single-slot design simplifies integration into standard industrial computers. The PCIe-AE304bp uses a PCIe Gen2 x4 interface and provides a robust connection for demanding automotive applications. Therefore, it offers a reliable alternative to conventional RJ45-based solutions in vibration-sensitive environments.
The PCIe-AE304bp operates fanlessly from -25°C to +70°C and supports Linux Ubuntu. Thanks to its rugged industrial design, it is well suited for automotive electronics testing and autonomous vehicle validation. In addition, the card can be used in next-generation edge AI systems.
