Description
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.
