9SQL4958CNDGI8

Overview

The Renesas 9SQL4958CNDGI8 is a PCIe clock generator designed for PCI Express applications. It features one circuit with a 1:4 input-to-output ratio, generating four differential outputs from a single clock input. The device operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 25MHz. It is housed in a 32-VFQFPN (5x5) package with an exposed pad, suitable for surface mount installation. The component functions reliably across an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix '8' against official documentation to confirm any unique configuration or packaging variations. Ensure the 32-VFQFPN footprint matches the target PCB design. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring a dedicated 25MHz PCIe clock source with four differential outputs. The 32-VFQFPN package offers a compact solution for space-constrained boards. Verify that the 3.135V–3.465V supply voltage aligns with the system power rails and that the -40°C to +85°C temperature range meets environmental requirements.

Part Context

This part belongs to Renesas' Application Specific Clock/Timing category, specifically tailored for PCI Express interfaces. It serves as a critical timing element in systems requiring precise clock distribution for PCIe lanes, ensuring signal integrity and compliance with interface standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas family. Verify if other models support the same 25MHz frequency and 1:4 ratio in a 32-VFQFPN package. Consult official substitution guides for confirmed equivalents.
