9SQ440NQQI

Overview

The Renesas 9SQ440NQQI is a programmable clock generator designed for Intel cloud and HPC platforms. It operates on a 3.3V supply with an operating temperature range of -40°C to +85°C. The device features 19 outputs, including dedicated pairs for 25MHz and 100MHz signals, and multiplexable MXCLK outputs. It supports PCIe Gen6 compliance and utilizes Low-Power HCSL (LP-HCSL) signaling. The component is housed in a 100-VFQFPN package measuring 8x8 mm.

Feature Summary

• PCIe Gen7 phase jitter performance below 18fs rms
• Includes 3 x 25MHz and 7 x 100MHz dedicated output pairs with individual OE# pins
• Supports selectable SMBus addresses and spread-spectrum amounts of 0%, -0.3%, and -0.5%
• Features Side-Band Interface for real-time hardware control

Applications

• Intel cloud computing platforms
• High-Performance Computing (HPC) systems
• Newer Intel-based server platforms

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and moisture sensitivity level. Ensure compatibility with system voltage requirements and thermal constraints before procurement. Confirm availability status as stock levels may vary by distributor.

Selection Notes

Select this component for applications requiring low-jitter clock generation for PCIe Gen6/Gen7 interfaces. Consider the LP-HCSL output type which eliminates external termination resistors, saving board area. Verify that the 100-VFQFPN package fits the design footprint and that the 3.3V supply aligns with the system power architecture.

Part Context

The 9SQ440 belongs to the CK440 series of main clock synthesizers. It is engineered to function as a complete clock solution or in combination with DB2000Q-compliant buffers. This integration allows for point-to-point clock distribution to multiple receiving agents within complex server architectures.
