9FGL0641AKILF

Overview

The 9FGL0641AKILF is a six-output, 3.3V PCIe Gen 1–6 clock generator designed for high-performance computing environments. It supports Common Clocked (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. The device features integrated terminations for both 100Ω and 85Ω systems, eliminating external resistors. Each output includes a dedicated OE# pin to support PCIe CLKREQ# functionality. It accommodates spread spectrum levels of 0%, -0.25%, and -0.5% via SMBus selection. The component operates within a temperature range of -40°C to +85°C and utilizes a space-saving 4mm × 4mm 24-VFQFPN package.

Procurement Notes

Verify the specific suffix 'KILF' against official Renesas documentation to confirm lead-free status and RoHS compliance. Ensure the selected variant matches the required voltage level and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and production lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring PCIe Gen 1–6 compliance with flexible clocking architectures. It is suitable for applications needing integrated impedance matching for both 100Ω and 85Ω traces. Consider this device if board space is constrained by its compact 4mm × 4mm footprint. Verify that the system requires independent output enables for power management via CLKREQ# signals.

Part Context

This device belongs to the IDT/Renesas 9FGL02/04/06/08 family of PCIe clock generators. These components are engineered for System-on-Chip (SOC) friendly designs, offering low power consumption and minimal external component requirements.
