9FGL699AKLF

Overview

The 9FGL699AKLF is a PCIe Gen 1–6 compliant clock generator manufactured by Renesas Electronics Corporation. It features two differential outputs supporting LP-HCSL signaling and one LVCMOS reference output with Wake-On-LAN support. The device accommodates Common Clocked (CC), Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. It operates on a single 3.3V supply voltage and integrates terminations for 100Ω and 85Ω systems to reduce external component count. The unit is housed in a compact 4mm × 4mm 24-VFQFPN package.

Feature Summary

• PCIe Gen 1–6 CC-compliant with support for SRNS and SRIS clocking architectures
• Two differential LP-HCSL outputs with dedicated OE# pins for CLKREQ# functionality
• Integrated terminations for 100Ω and 85Ω systems, eliminating four resistors per output
• SMBus-selectable spread spectrum options including CC/SRIS -0.25% and pin-selectable -0.5% spread

Applications

• Servers and High-Performance Computing systems
• NVMe Storage solutions
• Networking Accelerators
• Industrial Control applications

Procurement Notes

Verify the specific suffix 'KLF' against the manufacturer's current datasheet to confirm lead times and availability status. Confirm RoHS compliance and moisture sensitivity level requirements for your assembly process. Check for any recent Product Change Notices regarding packaging or material updates before finalizing procurement orders.

Selection Notes

Select this component when designing PCIe Gen 1 through Gen 6 interfaces requiring separate reference clocking with spread spectrum capabilities. Ensure the design supports the 3.3V core voltage and utilizes the 24-VFQFPN footprint. Verify that the integrated 100Ω/85Ω termination matches the target impedance of the PCB traces to minimize external passive components.

Part Context

This part belongs to the 9FGL02 series of 2-output 3.3V PCIe clock generators. It shares architectural similarities with models like the 9FGL0241 and 9FGL0251, offering comparable PCIe compliance and output configurations. The primary distinction lies in specific configuration options or manufacturing revisions denoted by the suffix.
