9FGL6241AQ301LTGI8

Overview

The 9FGL6241AQ301LTGI8 is a PCIe clock generator and buffer from Renesas Electronics, designed for high-speed serial link applications. It supports Common Clock (CC) and Separate Reference Independent Spread (SRIS) architectures, compliant with PCIe Gen 1 through Gen 6 standards. The device features two differential LP-HCSL outputs with integrated 100Ω terminations, eliminating the need for external resistors. It operates on a single 3.3V supply and includes SMBus-selectable spread spectrum capabilities (-0.5% or -0.25%) to reduce EMI. The component is housed in a compact 4mm x 4mm 24-VFQFPN package.

Feature Summary

• PCIe Gen 1–6 CC-compliant clock generation with SRIS support
• Two differential LP-HCSL outputs with integrated 100Ω termination resistors
• SMBus-selectable spread spectrum: -0.5% (default) or -0.25%
• Single 3.3V power supply operation

Applications

• PCIe Gen 1–6 host bridges and switches
• NVMe SSD controllers
• High-performance server motherboards
• Storage expansion cards

Procurement Notes

Verify the specific suffix LTGI8 against the manufacturer's current datasheet to confirm package type and moisture sensitivity level. Ensure compatibility with system power rails and SMBus addressing requirements before integration. Check for RoHS compliance documentation as required by regional regulations.

Selection Notes

Select this component when designing for PCIe Gen 1–6 architectures requiring low jitter and integrated output termination. Compare with the 9FGL6251 series if LVCMOS reference outputs or different input configurations are needed. Verify that the 100Ω internal termination matches the target PCB trace impedance requirements.

Part Context

This part belongs to the 9FGL02x1/04x1 family of intelligent PCIe clock generators. These devices are engineered to replace discrete clocking solutions, reducing board space and component count. The 9FGL6241 variant specifically provides two outputs, distinguishing it from quad-output models like the 9FGL0441.
