Renesas Launches Low-Jitter Clock Generator IC, Delivering High Performance, More Flexibility, and More Robustness

Renesas Electronics Corporation, a global supplier of semiconductor solutions, announced the launch of the low-jitter 9SQ440 clock generator IC, which is designed for next-generation Intel platforms for high-performance computing and data center applications. As the latest product in Renesas' rich PCIe product line, the 9SQ440 is the industry's first server clock generator that complies with the CK440Q standard. Developed for the Intel CK440Q specification and the requirements of future Intel® Xeon® processors, the 9SQ440 provides customers with a flexible, robust, high-performance synthesizer to meet the design challenges of PCIe Gen5.

Customers can combine the 9SQ440 with Renesas’ broad portfolio of PCIe clock solutions (including PCIe Gen5 clock buffers), infrastructure power supplies, and smart power stage (SPS) products to meet the needs of a complete data center solution.

“PCIe clock generators are at the heart of PCIe timing functionality. As the latest standards become more stringent, PCIe Gen5-compliant clock generators, such as the 9SQ440, provide customers with greater design flexibility and margin,” said Bobby Matinpour, Vice President of Data Center Business Unit, IoT and Infrastructure Business Unit at Renesas Electronics Corporation. “We are pleased to announce that Renesas has introduced the industry’s first mass-production-qualified products for PCIe Gen5 and PCIe Gen6-enabled devices, leveraging our superior timing technology and IP.”

9SQ440 can be used as a central clock generator for server CPU and PCIe clock. It has a total of 20 differential outputs and excellent jitter performance - less than 50fs RMS PCIe Gen5 universal clock phase jitter to meet the clock requirements of various topologies from simple single-board dual-slot to complex modular multi-slot systems.
