9FGL04P1A000KILFT

Overview

The 9FGL04P1A000KILFT is a 4-output, 3.3V PCIe Gen 1–6 clock generator from the 9FGL04x1 family. It supports Common (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. The device features LP-HCSL differential signaling with integrated 100Ω termination resistors for system simplification. Input frequencies range from 25 MHz to 25 MHz, supporting crystal or LVCMOS inputs. Output frequencies are configurable within 25 MHz to 25 MHz and 100 MHz to 100 MHz ranges. Key electrical parameters include a maximum common-clock jitter of 50 ps peak-to-peak and an output skew of 50 ps. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• PCIe Gen 1–6 compliant with support for CC, SRNS, and SRIS clocking architectures
• Integrated 100Ω differential termination resistors reduce external component count
• Pin-selectable spread spectrum levels including 0%, 0%, and -0.5% options
• SMBus-selectable -0.25% spread spectrum capability

Applications

• PCIe Gen 1 through Gen 6 high-speed serial link clocking
• Server and storage backplane systems requiring low-jitter reference clocks
• Industrial networking equipment utilizing SerDes interfaces

Procurement Notes

Verify the specific suffix 'KILFT' against official Renesas documentation to confirm package type, lead finish, and tape-and-reel specifications. Ensure compatibility with required moisture sensitivity level (MSL 3) and Pb-free category requirements for the target assembly process.

Selection Notes

Select this component when designing for PCIe Gen 1–6 standards requiring four independent outputs with integrated termination. Verify that the input frequency matches the available 25 MHz crystal or LVCMOS source. Confirm that the LP-HCSL output voltage levels (0.8V/3.3V) align with the receiving logic families in the design.

Part Context

This part belongs to the 9FGL04x1 series of clock generators designed for high-performance computing and communication applications. It shares architectural similarities with other members like the 9FGL0441DKILF but offers specific output configurations and spread spectrum options tailored for complex multi-lane serial links.

Replacement Considerations

Direct substitutes within the same family include the 9FGL0441DKILF. Verify pinout compatibility and specific output frequency capabilities before substitution. Cross-reference with the 9FGV1004CQ501LTGI8 if programmability is required, noting differences in output count and interface.
