9FGL02P1B000KILFT

Overview

The 9FGL02P1B000KILFT is a Renesas Electronics clock generator designed for PCIe Gen 1–6 applications. It features two differential outputs with LP-HCSL signaling and one LVCMOS reference output. The device supports Common Clocked (CC), Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. Integrated terminations for 100Ω and 85Ω systems reduce external component count. It operates on a single 3.3V supply, accepts crystal or LVCMOS inputs at 25 MHz or 100 MHz, and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• PCIe Gen 1–6 compliant with support for CC, SRNS, and SRIS clocking architectures
• Two differential LP-HCSL outputs and one 3.3V LVCMOS REF output with Wake-On-LAN support
• Integrated 100Ω and 85Ω termination resistors eliminate external components
• Pin-selectable spread spectrum levels: SRNS 0%, CC 0%, and CC/SRIS -0.5%
• SMBus-selectable CC/SRIS -0.25% spread spectrum option

Applications

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

Procurement Notes

Verify the specific suffix 'KILFT' against official Renesas documentation to confirm packaging type and tape/reel specifications. Confirm the operating temperature grade matches the design requirement, as variants exist for commercial and extended ranges. Ensure the input frequency configuration aligns with the available pin-strapping options for the selected architecture.

Selection Notes

Select this component when a dual-output PCIe clock solution with integrated termination is required for Gen 1 through Gen 6 interfaces. The choice between SRNS and SRIS architectures depends on the system's jitter budget and EMI requirements. Verify that the 3.3V core voltage and 25 MHz or 100 MHz crystal input frequencies match the target platform's oscillator capabilities.

Part Context

This part belongs to the 9FGL02-04-06-08 family of PCIe clock generators from Renesas. The '02' designation indicates two differential outputs, distinguishing it from quad (04) or octal (08) output variants in the same series. These devices are engineered to simplify board layout by integrating necessary impedance matching components directly onto the silicon die.

Replacement Considerations

Direct replacements within the same package and functionality include other members of the 9FGL02x1 series, such as the 9FGL0241DKILF or 9FGL0251DKILF, provided they meet the specific PCIe generation and temperature requirements.
