9FGL0251BKILF

Overview

The Renesas 9FGL0251BKILF is a 2-output 3.3V PCIe Gen 1–6 clock generator designed for high-performance computing applications. It supports LP-HCSL differential signaling with an output frequency range of 25 MHz to 100 MHz and consumes approximately 112 mW typ. The device integrates terminations for 100Ω and 85Ω systems, eliminating external resistors. It accommodates Common Clocked (CC), Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. Each output features a dedicated OE# pin for CLKREQ# functionality, and it includes one 3.3V LVCMOS REF output with Wake-On-LAN support.

Feature Summary

• PCIe Gen 1–6 CC-compliant with SRNS and SRIS clocking support
• Integrated terminations for 100Ω and 85Ω systems save 4 resistors per output
• Pin-selectable SRNS 0%, CC 0%, and CC/SRIS -0.5% spread spectrum levels
• SMBus-selectable CC/SRIS -0.25% spread spectrum level

Applications

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

Procurement Notes

Verify the specific suffix 'BKILF' against official Renesas documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Confirm current lifecycle status as distributors may list discontinued or obsolete inventory. Ensure moisture sensitivity level (MSL) handling procedures are followed upon receipt.

Selection Notes

Select this component when designing PCIe Gen 1 through Gen 6 interfaces requiring low-power, space-saving clock generation. The integrated termination resistors reduce bill-of-materials count. Verify that the required spread spectrum configuration matches the available pin-selectable or SMBus-selectable options provided by the device architecture.

Part Context

This part belongs to the 9FGL02-04-06-08 VersaClock family, specifically the 2-output variant. It shares architectural similarities with the 9FGL0451BKILF but differs in output count and package dimensions. The device utilizes a 4mm × 4mm 24-VFQFPN package, distinguishing it from higher-output models in the same series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for direct replacements or cross-reference with other 2-output PCIe clock generators if redesign is necessary.
