9FG108EFILF

Overview

The Renesas 9FG108EFILF is a clock synthesizer and jitter cleaner designed for high-performance computing applications. It features a single PLL circuit with a 1:9 input-to-output ratio, generating up to nine HCSL outputs from a single reference input. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies of 400MHz. Packaged in a 48-SSOP (BSSOP) housing, it is engineered for Intel CPU servers, PCI Express (PCIe), and SATA systems. The component integrates spread spectrum clock generation capabilities to reduce electromagnetic interference.

Feature Summary

• Generates up to 9 differential HCSL outputs from a single reference input
• Integrated PLL with spread spectrum clocking functionality
• Supports PCIe Gen 2 and SATA interface timing requirements
• Operates on a single 3.3V power supply (3.135V–3.465V)

Applications

• Intel CPU server platforms
• PCI Express (PCIe) bus clocking
• SATA storage controller interfaces

Procurement Notes

Verify the suffix 'FLF' corresponds to the tube packaging configuration rather than cut tape or reel variants. Confirm the specific temperature grade associated with this part number, as industrial variants may carry different suffixes. Ensure compatibility with existing PCB footprints for the 48-BSSOP package before procurement.

Selection Notes

Select this component when designing systems requiring multiple synchronized low-voltage differential outputs from a single source. The HCSL output type is suitable for direct interfacing with compatible receivers without additional level shifting. Consider the 400MHz frequency limit when evaluating system bandwidth requirements.

Part Context

This part belongs to the 9FG108 series of clock generators manufactured by Renesas Electronics. It is functionally related to other variants such as the 9FG108EFLFT, differing primarily in packaging format and potentially temperature rating. The base model 9FG108 serves as the core architecture for these specialized timing solutions.

Replacement Considerations

The 9FG108EFLFT is a verified alternative offering identical electrical specifications but supplied in cut tape or reel packaging instead of tubes. Cross-reference pinouts and electrical parameters to ensure interchangeability in existing designs.
