9SQL4954CNLGI8

Overview

The 9SQL4954CNLGI8 is a PCIe clock generator manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range of -40°C to 85°C. The device features one circuit with a 1:6 input-to-output frequency ratio, utilizing a PLL for clock generation. It accepts a 25MHz maximum input frequency and provides six differential outputs in a 40-VFQFPN (5x5mm) package with an exposed pad.

Feature Summary

• PCIe compliant clock generator with integrated PLL
• Six differential outputs derived from a single input
• Surface mount 40-VFQFPN package (5x5mm)
• Operates at 3.3V nominal with specified tolerance

Applications

• PCI Express timing solutions
• Server platforms
• High-performance computing systems

Procurement Notes

Verify the specific ordering suffix NLGI8 against official Renesas documentation to confirm packaging details such as reel or cut tape configuration. Confirm availability status as distribution data may vary. Ensure compliance with RoHS requirements before procurement.

Selection Notes

Select this component when a single reference clock needs to be distributed to six PCIe endpoints. Verify that the 25MHz input frequency matches the system design. Ensure the 40-VFQFPN footprint fits the PCB layout constraints.

Part Context

This part belongs to the Renesas PCIe clock generator family. It is designed to replace older discrete clocking solutions by integrating multiple outputs into a single low-jitter device, reducing board space and component count for PCIe architectures.

Replacement Considerations

Check for direct pin-compatible replacements within the same Renesas series. Verify electrical parameters such as jitter performance and output swing against the original design requirements.
