The PCIe 4.0 Switch chip is available in multiple configurations such as 104, 64, and 48 ports, supporting PCIe data rates of 2.5GT/s, 5GT/s, 8GT/s, and 16GT/s. It delivers a high-performance, low-latency, scalable, and cost-effective PCIe interconnect solution.

The product comes with a comprehensive software development kit (SDK), featuring simple and easy-to-use standard API interfaces that meet diverse development requirements for applications in data centers, AI servers, all-flash storage, and embedded systems. This significantly shortens time-to-market, reduces deployment risks and total cost of ownership (TCO), and enhances product competitiveness.
