Montage Technology PCIe 5.0/CXL 2.0 Retimer Chip in Mass Production

Montage Technology announced that its PCIe 5.0/CXL 2.0 Retimer has achieved mass production.

This chip is a key upgrade based on the firm‘s PCIe 4.0 Retimer, providing a stable and reliable PCIe 5.0 and CXL 2.0 interconnect solution with high bandwidth and low latency for the cloud and HPC markets.

The company‘s PCIe 5.0/CXL 2.0 Retimer employs signal conditioning technologies to improve signal integrity and increase the effective transmission distance of high-speed signals. Compliant with relevant PCI-SIG and CXL specifications, the chip meets mainstream package requirements, supports transfer rate up to 32GT/s, and takes the lead in supporting transmission latency of less than 5ns. It chip supports various complex system topologies such as SRIS and Retimer cascading, offering a solution to address the PCIe/CXL signal integrity challenges in next-gen servers, enterprise storage, and AI acceleration systems. The PCIe 5.0/CXL 2.0 Retimer has passed interoperability testing with a variety of compute, storage and networking products, such as CPU, PCIe switches, SSDs, GPUs and NICs, thus laying a foundation for the large-scale deployment of cloud computing and data centers.

“PCIe 5.0 and CXL interconnect technologies are the cornerstones of building cloud computing and data center infrastructure, which will significantly promote the application requirements of Retimer in AI servers and storage systems. Looking forward, Montage will continue to work closely with CPU,GPU, NIC, SSD, and PCIe/CXL equipment manufacturers, constantly updating and expanding our product portfolios, and make unremitting efforts to improve the performance of artificial intelligence, machine learning and cloud computing systems,” said Mr. Stephen Tai, president.

For typical application scenarios such as AI servers, NVMe SSDs and Riser Cards, the company provides technical supports, such as PCIe 5.0/CXL 2.0 Retimer-based reference design, evaluation board, and supporting software, to help customers complete the design-in and shorten the product launch cycle.
