Kvaser has introduced the PCIe 4xLIN, a compact four-channel LIN interface designed for deterministic communication, precise timing analysis, and scalable validation setups. Built for desktop, industrial, and HIL environments, the low-profile PCIe card combines galvanic isolation with synchronized timestamping, giving engineers reliable system-level visibility when testing and debugging LIN networks.
The Kvaser PCIe 4xLIN offers four individually galvanically isolated LIN channels on a single PCIe card. Powered by FPGA-based Kvaser LIN-IP technology, it supports communication speeds of up to 20 kbaud with 1 µs timestamp resolution.
That makes it easier for developers to capture timing-sensitive events with high precision and improve visibility during debugging and validation.
It also works alongside multiple Kvaser interfaces, allowing test setups to scale as system complexity increases.
Easier integration with existing tools
The PCIe 4xLIN is fully compatible with applications built on the standardized Kvaser LINlib API, so it fits into existing setups without requiring software changes.
Applications originally developed for other Kvaser LIN hardware can run without modification, helping teams move quickly between projects and interfaces.
It supports both Windows and Linux and works with the Kvaser CANlib SDK, which includes LINlib and other APIs, along with examples for C, C++, C#, Python, Delphi, and Visual Basic.
The card installs directly into a PCI Express slot and draws power from the host system, which reduces cabling and simplifies integration in compact systems and test racks.
Time synchronization support
The PCIe 4xLIN also includes Kvaser’s software-based TimeSync, helping engineers keep timestamps aligned across multiple devices and systems.
In distributed test environments, this makes it easier to correlate events across LIN and CAN networks while reducing the need for manual log analysis.
On Linux, the interface exposes a PHC device for time synchronization to a host-referenced clock source, using standard tools such as phc2sys. That provides a solid foundation for synchronized logging, automated testing, and accurate event analysis across connected systems.
Built for harsh conditions
Kvaser designed the PCIe 4xLIN for industrial and embedded use, with an operating temperature range of –40 °C to +85 °C. Its low-profile PCIe design includes both short and long mounting brackets, offering flexibility during installation.
A single 26-pin high-density D-SUB connector provides access to all four LIN channels, helping keep system designs compact.
Typical use cases include ECU development, automotive body electronics, HIL testing, 
multi-channel logging, and industrial LIN communication systems.
Leadership Comment
Thomas Roberts, Kvaser’s CCO comments: “LIN continues to play a critical role in modern vehicle architectures, particularly as the number of distributed electronic functions grows. As systems scale, the challenge isn’t just accessing LIN data but in capturing and correlating it reliably across channels and interfaces. That’s exactly what the PCIe 4xLIN is designed to address.”
Availability
The Kvaser PCIe 4xLIN will be available from July 2026.
