Valens Launches Ultra-High-Speed Automotive Chipset

Valens, a leader in ultra-high-speed in-vehicle connectivity, has unveiled its latest automotive chipset – the VA608A. The chipset claims to provide the high-speed bandwidth and resilience required for the many applications in the connected and autonomous car.

According to the company, the chipset delivers data transmission speeds of up to 16Gbps and enables automakers to extend native PCIe as a long-distance in-vehicle connectivity technology – up to 15m/50ft. The VA608A also enables 2.5Gb Ethernet over a single Unshielded Twisted Pair (UTP) wire with near-zero latency.

With the VA608A, The company is introducing an innovative concept for long-distance PCIe connectivity, enabling OEMs and Tier-1s to utilize a wide array of existing components without requiring a complete redesign of the vehicle’s architecture.

This leads to reduced costs and wiring complexity, and the ability to utilize more powerful technologies with increased speed and functionality. PCIe extension technology is designed for many use cases in the vehicle including telematics, multi-modem smart antennas (5G, WiFi, WiGig, BT, etc.), ECU-to-ECU connectivity, and shared storage/black box storage. It also significantly simplifies high-speed, low latency, power-efficient backbone architecture.

Valens claims its technology is a scalable solution specifically designed to handle harsh EMI and environmental interference in the vehicle landscape. The VA608A is an ASIC prototype and is currently available. The VA608A launch comes on the heels of the MIPI Alliance’s selection of Valens’ technology as the baseline for its A-PHY standard for ultra-high-speed in-vehicle video transmission. MIPI’s A-PHY specification defines an asymmetric physical layer for the automotive market to provide high-speed links for cameras, displays and sensors, through native CSI-2 and DSI/DSI-2 interfaces, addressing autonomous applications.

The final specification is expected to be completed by the end of 2019. MIPI’s will be the first high-speed asymmetric standard in the market.
