9FGV0241AKLF

Overview

The 9FGV0241AKLF is a PCI Express (PCIe) clock generator and fan-out buffer manufactured by Renesas Electronics Corporation. It features an integrated Phase-Locked Loop (PLL) to generate up to three differential outputs from a single crystal input, operating at frequencies up to 100MHz. The device supports HCSL and LVCMOS output types and functions within a supply voltage range of 1.7V to 1.9V. Designed for surface mount assembly, it is housed in a compact 24-VFQFN package with exposed pads, measuring 4x4mm. The component operates reliably within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrated PLL-based clock generation supporting PCIe applications
• Single crystal input to three differential output configuration
• HCSL and LVCMOS compatible output drivers
• Low voltage operation between 1.7V and 1.9V

Applications

• PCI Express (PCIe) system clock distribution
• Frequency generation for high-speed digital interfaces
• Fan-out buffering for timing-critical circuits

Procurement Notes

Verify the specific suffix 'AKLF' against the manufacturer's datasheet to confirm pinout, packaging, and RoHS compliance status. Ensure the required operating temperature range aligns with the commercial grade specification (0°C to 70°C). Cross-reference the 24-VFQFN footprint dimensions during PCB layout design to ensure mechanical compatibility.

Selection Notes

Select this component when a low-jitter, single-input clock source is required for PCIe architectures. Confirm that the load requirements match the HCSL or LVCMOS drive capabilities. Verify that the 100MHz maximum frequency meets the system timing needs. Consider the 24-QFN package size constraints relative to available board space.

Part Context

This part belongs to the 9FGV0241 family of clock generators. Variants such as 9FGV0241AKILF offer extended industrial temperature ranges (-40°C to 85°C), while 9FGV0241AKLFT provides tape-and-reel packaging. The base model number remains consistent across these variations, differing primarily in environmental ratings and shipping formats.

Replacement Considerations

Direct substitutes include other variants within the 9FGV0241 series, such as 9FGV0241AKILF for industrial temperature requirements. Ensure any replacement maintains the 24-VFQFN package and 1:3 ratio configuration.
