9FGL6241AQ302LTGI8

Overview

The 9FGL6241 is a two-output, 3.3V PCIe Gen 1–6 clock generator designed for Common Clock (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. It features integrated terminations for 100Ω and 85Ω systems, eliminating external resistors. The device supports SMBus-selectable spread spectrum modulation levels of 0%, -0.5%, and -0.25%. Each output includes a dedicated OE# pin for PCIe CLKREQ# functionality. It operates with a typical power consumption of 112mW and utilizes a space-saving 4mm × 4mm 24-VFQFPN package.

Feature Summary

• Supports PCIe Gen 1–6 CC, SRNS, and SRIS clocking architectures
• Integrated terminations for 100Ω and 85Ω systems save four resistors per output pin
• SMBus-selectable spread spectrum: 0%, -0.5%, and -0.25%
• One 3.3V LVCMOS REF output with Wake-on-LAN (WOL) support

Applications

• PCIe Gen 1–6 compliant system designs
• Common Clocked (CC) architecture implementations
• Separate Reference No Spread (SRNS) applications
• Separate Reference Independent Spread (SRIS) applications

Procurement Notes

Verify the specific suffix LTGI8 against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required operating voltage ranges and temperature specifications before procurement. Cross-reference part numbers carefully as suffixes often dictate packaging or environmental ratings rather than functional changes.

Selection Notes

Select this component when designing for PCIe Gen 1 through Gen 6 standards requiring flexible clocking modes. It is suitable for systems needing integrated termination resistors to reduce board space. Consider the 24-VFQFPN package for compact layouts. Verify that the required spread spectrum settings align with the device's SMBus-configurable options.

Part Context

The 9FGL6241 belongs to the 9FGL0241/51 family of intelligent PCIe clock generators. These devices are engineered for high-performance computing and storage applications where precise clocking and low jitter are critical. The family supports various PCIe generations and offers configurable spread spectrum to minimize EMI.

Replacement Considerations

Check for direct substitutes within the 9FGL series or other Renesas PCIe clock generators. Verify pinout compatibility and electrical parameters such as supply voltage and output signaling types. Ensure any replacement supports the same PCIe generation and clocking architectures.
