Óscar Ciordia, marketing and sales director of KD added: “Japan is a highly advanced automotive market with strong technology leadership across OEMs and Tier-1 suppliers. We are honored to collaborate with Hitachi High-Tech as a business partner to better serve this market. This agreement represents an important milestone and a clear signal that optical multigigabit in-vehicle connectivity is gaining momentum in Japan. The collaboration is expected to accelerate adoption of optical networking across the Japanese automotive ecosystem.”
Focus on KD7251: Integrated Optoelectronics for Automotive Networks
Under the agreement, Hitachi High-Tech will support the introduction of KD7251, an optoelectronic device for high-speed in-vehicle data transmission. The device is designed for automotive network platforms that support ADAS, infotainment, and emerging software-defined vehicle architectures.
KD7251 combines optical and electronic functionality in a single device to support multigigabit in-vehicle links. The device helps automotive system designers manage bandwidth growth, electromagnetic interference (EMI) constraints, and packaging efficiency in zonal and centralized vehicle architectures. The ASIC implements BASE-AU physical layers and complies with IEEE Std 802.3cz for automotive multigigabit optical communication over OM3 multi-mode glass fiber.
The KD7251 supports data rates of 2.5, 5, and 10 Gb/s for in-vehicle optical links. Its integrated bridging enables direct connectivity for MIPI-based sensors such as cameras and radar (CSI-2), displays (DSI-2), and AI processors via PCIe.
