9FGL0441BKILFT

Overview

The Renesas 9FGL0441BKILFT is a 3.3V PCIe Gen 1–6 clock generator designed for high-speed serial link applications. It operates within a -40°C to +85°C temperature range and utilizes a 32-pin VFQFPN package (NLG32). The device supports Common Clock (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. Key electrical parameters include a maximum core voltage of 3.3V, differential output signaling via LP-HCSL, and an output impedance of 100Ω. It accepts crystal or LVCMOS inputs at 25 MHz and provides up to five outputs with a maximum peak-to-peak common-clock jitter of 50 ps.

Feature Summary

• Supports PCIe Gen 1 through Gen 6 compliance standards.
• Offers selectable SRNS and SRIS clocking architectures.
• Integrates spread spectrum capability for EMI reduction.
• Features low-power HCSL (LP-HCSL) differential outputs.

Applications

• PCI Express (PCIe) Gen 1–6 interface clocking
• SerDes clock generation
• High-performance computing systems

Part Context

This component belongs to the 9FGL04xx series of PCIe clock generators from Renesas Electronics. These devices are engineered to meet the stringent jitter and timing requirements of modern high-speed interconnects. The specific suffix 'BKILFT' denotes the 3.3V variant in the 32-pin VFQFPN package with lead-free termination.

Replacement Considerations

Direct replacements must match the 3.3V supply, 32-pin VFQFPN package, and PCIe Gen 1–6 support. Verify that alternative parts support the required SRNS/SRIS modes and LP-HCSL output signaling. Cross-reference pinouts and thermal characteristics to ensure compatibility.
