ICS9FG108DGLFT

Overview

The ICS9FG108DGLFT is a clock frequency synthesizer manufactured by Renesas Electronics Corporation, designed for Intel CPU servers, PCI Express (PCIe), and SATA applications. It features a single circuit with a 1:9 input-to-output ratio, supporting HCSL outputs. The device operates at a maximum frequency of 400MHz with a supply voltage range of 3.135V to 3.465V. It accepts clock or crystal inputs and supports differential outputs. Packaged in a 48-TFSOP (48-TSSOP) surface-mount case, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated PLL-based clock frequency generator optimized for PCIe and SATA timing
• Provides one-to-nine output ratio with HCSL signal levels
• Supports both clock and crystal input configurations
• Operates on a 3.135V to 3.465V power supply

Applications

• Intel CPU server systems
• PCI Express (PCIe) interface timing
• SATA storage controller synchronization

Procurement Notes

Verify the specific ordering suffix DGLFT against official Renesas documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the component matches the required 48-TFSOP form factor and commercial temperature grade for the target design.

Selection Notes

Select this component when a 1:9 fan-out configuration with HCSL outputs is required for PCIe or SATA buses. Confirm that the 400MHz maximum frequency meets system bandwidth requirements and that the 0°C to 70°C operating range aligns with the environmental constraints of the host equipment.

Part Context

This part belongs to the 9FG108 series of clock generators from Renesas. It serves as a specialized timing solution for high-speed serial interfaces, providing stable frequency synthesis for data transmission links in server and storage architectures.

Replacement Considerations

Check for direct pin-compatible alternatives within the same 9FG108 family, such as variants with different temperature ranges or packaging options, ensuring identical electrical parameters and output configurations.
