9FGL04P1B000KILFT

Overview

The 9FGL04P1B000KILFT is a four-output PCIe Gen 1–6 clock generator from Renesas Electronics. It operates on a single 3.3V supply and supports Common Clock (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. The device provides four differential LP-HCSL outputs and one LVCMOS reference output with Wake-on-LAN support. It features integrated terminations for 100Ω and 85Ω systems, reducing external component count. Key specifications include a maximum common-clock jitter of 50ps peak-to-peak and an operating temperature range of -40°C to +85°C.

Feature Summary

• PCIe Gen 1–6 compliance supporting CC, SRNS, and SRIS clocking architectures
• Four differential LP-HCSL outputs with integrated 100Ω/85Ω terminations
• SMBus-selectable spread spectrum options: 0%, -0.5%, and -0.25%
• Single 3.3V LVCMOS reference output with Wake-on-LAN capability

Applications

• PCIe Gen 1 through Gen 6 compliant system designs
• High-performance computing platforms requiring low-jitter clocking
• Server and storage infrastructure baseboards

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging versus 'LF' tray packaging in official documentation. Confirm lead-free status and RoHS compliance details directly from the manufacturer datasheet before procurement. Ensure the specific variant matches the required output configuration and package type for the target application.

Selection Notes

Select this component for designs requiring four independent PCIe clock outputs with integrated termination resistors. Verify that the input frequency requirements align with the supported crystal or LVCMOS input ranges. Consider the SMBus programmability for spread spectrum needs to meet EMI regulations without external components.

Part Context

This part belongs to the 9FGL04x1 family of PCIe clock generators. It shares architectural similarities with other members like the 9FGL02x1 and 9FGL08x1 series, differing primarily in the number of outputs. The family targets high-speed serial interface applications requiring precise clock synchronization and low jitter performance.

Replacement Considerations

Direct replacements within the same family include the 9FGL0441DKILF for similar 4-output configurations. Cross-family alternatives may include the 9FGV1004CQ501LTGI8 for programmable PhiClock applications, though pinouts and features differ. Always verify electrical parameters and package dimensions before substitution.
