Valens introduces long-range PCIe connectivity in vehicles
Valens announced the launch of its PCIe Module, an evaluation platform to demonstrate the long-distance transmission of PCIe data over an HDBaseT Automotive link. HDBaseT Automotive's ability to extend PCIe signals is aimed at simplifying complex in-vehicle architectures by optimizing resource sharing of electronic control units (ECUs), communication devices, and solid-state drives (SSDs). HDBaseT Automotive reportedly enables symmetric tunneling of data, with native networking capabilities over a single unshielded twisted pair (UTP) cable for up to 15 m (50 ft). A key application for the PCIe Module are smart antennas and telematics, as HDBaseT Automotive can connect the numerous antennas on top of a car to an ECU located in a more environmentally friendly location than the roof, with only unshielded twisted pair (UTP) cables. The PCIe Module can also converge other interfaces over the same cable (such as I2S, UART, and side-band signals), as part of the telematics unit. The PCIe Module can be connected to legacy PCIe devices, switches, or bridges. The PCIe protocol can be used as a high-speed, low latency, power-efficient backbone. The HDBaseT Automotive PCIe Module will be available for customers as of Q3 2018.
