9FGL6241AP301NDGI

Overview

The 9FGL6241AP301NDGI is a PCI Express (PCIe) clock generator IC from Renesas Electronics, part of the 9FGL6241 series. It operates with a single output and supports frequencies up to 100MHz. The device utilizes a 28-VFQFPN (4x4mm) package with an exposed pad for surface mount installation. It features integrated PLL circuitry and supports LP-HCSL and LVCMOS output signaling types. The component is designed for applications requiring precise clock generation within PCIe architectures, operating within a temperature range of -40°C to 85°C.

Feature Summary

• Supports PCIe Gen 1-6 Common Clock (CC), Separate Reference No Spread (SRnS), and Separate Reference Independent Spread (SRIS) architectures.
• Integrated terminations for 100Ω systems save external resistors.
• SMBus-selectable spread spectrum options including 0%, -0.5%, and -0.25%.
• Features one open-drain CC_IR output indicating PCIe clock mode.

Applications

• Single and dual-ported NVMe SSDs
• PCIe master/slave clocking applications
• Clock multiplexing systems

Procurement Notes

Verify the specific suffix 'NDGI' against the manufacturer's official documentation to confirm packaging details and RoHS compliance status. Ensure the ordering information matches the exact pinout and electrical specifications required for the target design, as suffixes may indicate variations in tape-and-reel quantities or environmental certifications.

Selection Notes

Select this component when a single differential output is sufficient for the PCIe link. Compare the 100Ω integrated termination option against the 85Ω variant (9FGL6251 series) based on the PCB trace impedance requirements. Confirm that the 28-VFQFPN package dimensions fit the available board space constraints.

Part Context

This part belongs to the 9FGL62xx intelligent PCIe clock buffer/generator family. These devices are optimized for high-speed serial interfaces like NVMe and standard PCIe slots. The 9FGL6241 series specifically provides single-output configurations, distinguishing it from multi-output counterparts in the same product line.

Replacement Considerations

Direct substitutes include other members of the 9FGL6241 series with different suffixes for packaging variations. For designs requiring 85Ω outputs, the 9FGL6251 series serves as a functional alternative with adjusted output impedance characteristics.
