概要
説明
The 9SQ445 is a CK440Q Lite clock synthesizer for newer Intel-based server platforms. The 9SQ445 is a single-chip, PCIe Gen6 compliant device. It is designed to work as a complete clock solution, or in combination, with DB2000Q-compliant or other clock buffers to provide point-to-point clocks to multiple receiving agents.
特長

Comparing PCI Express® Gen 3-6 Jitter Filters to a 12k-20M Jitter Filter
This video provides a brief comparison of PCIe Gen3-6 common clock jitter filters vs. a typical 12k to 20MHz jitter filter plot. The tutorial explains what noise frequencies PCIe Gen6 is most sensitive to, and why it's important to minimize jitter in the 1MHz to 50MHz region. Presented by Ron Wade, system architect at Renesas.
