9FGL0241BKILF

Overview

The 9FGL0241BKILF 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. Each output includes a dedicated OE# pin supporting PCIe CLKREQ# functionality. The device supports SMBus-selectable spread spectrum levels of -0.25% or pin-selectable options including 0% and -0.5%. It operates from a single 3.3V supply, consumes approximately 112mW, and accepts a 25MHz crystal or LVCMOS input.

Feature Summary

• PCIe Gen 1–6 compliance with support for CC, SRNS, and SRIS clocking architectures
• Integrated 100Ω and 85Ω termination resistors reduce component count by four per output
• Pin-selectable SRNS 0%, CC 0%, and CC/SRIS -0.5% spread spectrum; SMBus-selectable -0.25% spread
• Dedicated OE# pins on each differential output enable PCIe CLKREQ# functionality

Applications

• Servers and High-Performance Computing platforms
• NVMe Storage subsystems
• Networking Accelerators
• Industrial Control systems

Procurement Notes

Verify the specific suffix BKILF against the manufacturer's current datasheet to confirm package dimensions and marking details. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL) ratings prior to assembly planning. Check for any Product Change Notifications (PCN) related to packaging or material updates. Ensure design-in documentation matches the exact part number variant to avoid interface mismatches.

Selection Notes

Select this component when designing PCIe Gen 1 through Gen 6 interfaces requiring separate reference clocks with spread spectrum capabilities. The integrated termination resistors make it suitable for space-constrained layouts where saving board area is critical. Verify that the system requires 3.3V I/O compatibility and LP-HCSL signaling levels. Ensure the application utilizes a 25MHz reference frequency source compatible with the crystal or LVCMOS input requirements.

Part Context

This device belongs to the 9FGL02xx series of PCIe clock generators. It shares architectural similarities with other members like the 9FGL0451 and 9FGL0841 but differs in output count and specific termination configurations. The 9FGL0241 variant specifically targets dual-output applications, distinguishing it from single-output or higher-output counterparts within the same family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Designers should consult Renesas Electronics for direct cross-reference recommendations based on specific electrical and mechanical constraints.
