As part of the collaboration, Hitachi High-Tech will support the launch of KD's KD7251, an integrated optoelectronic device for high-speed in-vehicle data transmission. The transceiver is designed for demanding automotive environments and enables the transition to scalable, future-proof network platforms for ADAS, infotainment and software-defined vehicle architectures.

For High Bandwidths

The KD7251 combines optical and electronic functions in one component and enables robust multi-gigabit connections. At the same time, it supports system developers in the automotive sector in coping with increasing bandwidth requirements, restrictions due to electromagnetic interference and packing density requirements in zonal and centralized vehicle architectures. The ASIC implements the BASE-AU physical layer and is compliant with the IEEE Std 802.3cz specification for multigigabit optical links over multimode fiber.

As a single-chip solution with an integrated optical interface, the component supports data rates of 2.5, 5 and 10 Gbit/s. It also has bridging functions that enable the direct connection of MIPI-based sensors such as cameras and radar, displays and AI processors via PCIe, thus simplifying system integration in the vehicle.
