9FGL0241BKILFT

Overview

The 9FGL0241BKILFT is a 2-output 3.3V PCIe Gen 1–6 clock generator designed for Common Clocked (CC), Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. It features LP-HCSL differential outputs with integrated terminations for 100Ω and 85Ω systems, eliminating external resistors. The device supports pin-selectable spread spectrum levels of 0%, -0.5%, and SMBus-selectable -0.25%. Each output includes a dedicated OE# pin for PCIe CLKREQ# functionality. It operates on a single 3.3V supply with typical power consumption of 112mW, housed in a space-saving 4mm × 4mm 24-VFQFPN package.

Feature Summary

• Supports PCIe Gen 1–6 CC, SRNS, and SRIS clocking architectures

• Pin-selectable SRNS 0%, CC 0%, and CC/SRIS -0.5% spread; SMBus-selectable -0.25% spread
• Dedicated OE# pins support PCIe CLKREQ# functionality

Applications

• Servers and High-Performance Computing
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control Systems

Procurement Notes

Verify the specific suffix 'BKILFT' against the manufacturer's official datasheet to confirm package type, lead finish, and environmental compliance status. Ensure the ordering code matches the required spread spectrum configuration options and voltage specifications before procurement.

Selection Notes

Select this component for designs requiring PCIe Gen 1 through Gen 6 clock generation with flexible spread spectrum control. It is suitable for applications needing integrated termination resistors to reduce board space and BOM count. Verify that the system requires 3.3V operation and LP-HCSL output signaling compatible with the target PCIe endpoints.

Part Context

The 9FGL0241BKILFT belongs to the Renesas 9FGL series of PCIe clock generators. This family provides low-jitter clock solutions optimized for high-speed serial interface standards. The device integrates multiple clocking architectures into a single package, simplifying design implementation for complex server and storage platforms.

Replacement Considerations

Check for direct substitutes within the 9FGL series or other Renesas PCIe clock generators with similar output counts and voltage requirements. Verify compatibility of pinouts and electrical parameters if considering cross-brand alternatives.
