9FG108EFLFT

Overview

The Renesas 9FG108EFLFT is a clock/frequency synthesizer IC designed for Intel CPU servers, PCI Express (PCIe), and SATA applications. It features an internal PLL and operates as a spread spectrum clock generator with one circuit providing nine outputs at a 1:9 input-to-output ratio. The device accepts clock or crystal inputs and delivers HCSL output signals. It supports maximum frequencies up to 400MHz and functions within a supply voltage range of 3.135V to 3.465V. The component is rated for commercial temperatures from 0°C to 70°C and is housed in a 48-BSSOP package.

Feature Summary

• Integrated PLL-based frequency synthesis for PCIe and SATA clocking
• Single circuit generating nine differential HCSL outputs
• Spread spectrum clock generation capability
• Compatible with Intel CPU server architectures

Applications

• Intel CPU Server systems
• PCI Express (PCIe) clock distribution
• SATA interface timing

Procurement Notes

Verify the specific suffix 'FLFT' against the manufacturer's current datasheet to confirm package dimensions and RoHS compliance status. Check for any Product Change Notifications (PCNs) regarding marking or material changes. Ensure the 48-BSSOP footprint matches the target PCB design. Confirm availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a single-input, nine-output HCSL clock solution is required for PCIe or SATA buses. Verify that the 400MHz maximum frequency meets system requirements. Ensure the 3.3V nominal supply voltage aligns with the board design. Consider the 48-SSOP package size constraints during layout planning.

Part Context

This part belongs to the 9FG108 family of clock generators. Variants such as 9FG108EGLFT utilize a 48-TFSOP package instead of BSSOP. The base model number 9FG108 indicates the core functionality, while suffixes define packaging and environmental ratings. It serves as a dedicated timing source for high-speed serial interfaces.

Replacement Considerations

The 9FG108EGLFT is a pin-compatible alternative differing primarily in the 48-TFSOP package versus the 48-BSSOP. Verify mechanical fit before substitution. No other direct functional replacements are documented in the provided data.
