9FGL04P1AKILFT

Overview

The 9FGL04P1AKILFT is a 3.3V PCIe Gen 1–7 clock generator manufactured by Renesas Electronics Corporation. It features four differential outputs utilizing LP-HCSL signaling and one LVCMOS output, housed in a 32-lead VFQFPN package (5.0 x 5.0 mm). The device supports Common Clocked (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures compliant with PCIe Gen 1 through Gen 7 standards. It operates within a temperature range of -40°C to +85°C and accepts crystal or LVCMOS inputs at frequencies such as 25 MHz.

Feature Summary

• Supports PCIe Gen 1–7 CC, SRNS, and SRIS clocking architectures
• Four differential LP-HCSL outputs and one LVCMOS output
• Integrated termination resistors for direct connection to 100Ω or 85Ω transmission lines
• Spread spectrum tolerance for EMI reduction

Applications

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

Part Context

This component belongs to the 9FGL04x1D family of PCIe clock generators from Renesas. The 'P1' suffix indicates factory-programmable SMBus configuration options for power-up defaults. It is part of the broader 9FGL02/04/06/08 series designed for space-constrained designs using 4mm x 4mm or 5mm x 5mm packages.

Replacement Considerations

Direct replacements within the same family include the 9FGL0441DKILFT or 9FGL0451DKILFT, depending on whether 100Ω or 85Ω integrated terminations are required. Verify that the substitute part supports the specific PCIe generation requirements and output count needed for the design.
