9FGL04P1A000KILF

Overview

The 9FGL04P1A000KILF is a 4-output, 3.3V PCIe Gen 1–6 clock generator manufactured by Renesas Electronics Corporation. It supports Common Clocked (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. The device features LP-HCSL differential signaling with integrated terminations for 100Ω and 85Ω systems, eliminating external resistors. It operates with a 25 MHz or 100 MHz input frequency and consumes approximately 112 mW of power. The component is housed in a space-saving 5mm × 5mm 32-VFQFPN package.

Feature Summary

• Supports PCIe Gen 1–6 CC, SRNS, and SRIS clocking architectures
• Integrated terminations for 100Ω and 85Ω systems reduce component count
• Pin-selectable spread spectrum options: 0%, -0.5%, and SMBus-selectable -0.25%
• Dedicated OE# pins on outputs support PCIe CLKREQ# functionality

Applications

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

Part Context

The 9FGL04P1A000KILF belongs to the 9FGL04x1 series of intelligent PCIe clock generators. This family provides low-jitter clocking solutions compliant with PCI Express specifications from Generation 1 through Generation 6. The series includes variants with different output counts and packaging options to suit various board density requirements.

Replacement Considerations

Direct replacements within the same family include other 9FGL04x1 variants such as the 9FGL0441DKILF, which shares similar architectural features but may differ in specific pin configurations or spread spectrum settings. Verify pin compatibility and electrical parameters before substitution.
