9SQ440NQQI8

Overview

The 9SQ440NQQI8 is a programmable clock generator from the Renesas 9SQ440 series, designed for Intel cloud and HPC platforms. It serves as a main clock synthesizer compliant with PCIe Gen6 standards. The device features 20 differential outputs utilizing Low-Power HCSL signaling, operating at frequencies up to 100 MHz. Powered by a single 3.3 V supply, it consumes approximately 875 mW. The component is housed in a 100-VFQFPN package (8x8 mm) and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• PCIe Gen6 compliant single-chip clock synthesizer for server platforms
• 20 differential LP-HCSL outputs eliminating external termination resistors
• Supports spread-spectrum generation with selectable amounts (0%, -0.3%, -0.5%)
• Integrated SMBus interface with 9 selectable addresses for hardware control

Applications

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

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging variations. The '8' suffix typically indicates reel or cut-tape packaging, whereas other suffixes may denote tray quantities. Confirm moisture sensitivity levels and lead-free status prior to procurement to ensure compliance with assembly requirements.

Selection Notes

Select this component for designs requiring low-jitter clock distribution for PCIe Gen6 interfaces. Ensure the design accommodates the 3.3 V supply voltage and the thermal dissipation characteristics of the 100-VFQFPN package. Verify that the required output frequencies fall within the 100 MHz maximum limit and that LP-HCSL signaling matches the receiving agents' input specifications.

Part Context

The 9SQ440 belongs to the CK440 family of clock generators optimized for high-speed data transmission. It is engineered to replace older clock solutions by integrating multiple output buffers into a single chip, reducing board space and complexity. The device complements buffer components like the DB2000Q for expanded point-to-point clocking needs.
