9FGL839AKILF

Overview

The 9FGL839AKILF is a clock synthesizer manufactured by Renesas Electronics Corporation, designed for high-performance timing applications. It operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 200MHz. The device features a single circuit with a 1:1 input-to-output ratio, utilizing LVCMOS or crystal inputs and HCSL outputs. It is housed in a 48-VFQFN exposed pad package, suitable for surface mount installation. The component functions across an operating temperature range of -40°C to 85°C, ensuring reliability in demanding environments.

Feature Summary

• Provides precise clock signal synthesis for system timing requirements
• Supports differential output configurations for noise reduction
• Integrates low-jitter performance for data integrity

Applications

• PCI Express (PCIe) infrastructure timing
• Server and storage system clock distribution
• High-speed communication equipment synchronization

Procurement Notes

Verify the specific suffix 'AKILF' against the official Renesas datasheet to confirm package type and RoHS compliance status. Confirm that the 48-VFQFN package matches the design-in requirements. Check for any recent Product Change Notices (PCN) regarding assembly sites or material changes. Ensure the source document explicitly lists this part number as active or end-of-life to manage lifecycle risks appropriately.

Selection Notes

Select this component when a dedicated clock synthesizer with HCSL outputs is required for PCIe or similar high-speed interfaces. Consider the 48-pin footprint for board space constraints. Verify input frequency compatibility with the available crystal or LVCMOS sources. Evaluate the thermal performance of the exposed pad package for the intended application environment.

Part Context

This part belongs to the FemtoClock series of clock generators and synthesizers from Renesas. It is engineered to provide low-phase jitter and flexible configuration options for modern digital systems. The 9FGL839AKILF specifically targets applications requiring robust clock distribution with minimal signal degradation over multiple traces.

Replacement Considerations

Consult the Renesas replacement guide for direct pin-compatible alternatives if this part is discontinued. Verify electrical specifications such as output swing and input thresholds before substituting with other clock synthesizers.
