9FG104EFLFT

Overview

The Renesas 9FG104EFLFT is a clock frequency synthesizer and jitter cleaner designed for Intel CPU servers, PCI Express (PCIe), and SATA applications. It features an integrated Phase-Locked Loop (PLL) to generate stable clock signals with a maximum output frequency of 400MHz. The device accepts clock or crystal inputs and provides five HCSL outputs in a 28-SSOP package. It operates within a supply voltage range of 3.135V to 3.465V and supports an industrial temperature range of -40°C to 85°C.

Feature Summary

• Integrated PLL-based clock synthesis and jitter cleaning
• Maximum output frequency of 400MHz
• Five HCSL differential outputs
• Supports crystal or clock input sources

Applications

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

Procurement Notes

Verify the specific suffix 'EFLFT' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Check for Product Change Notifications (PCNs) regarding packaging or material changes. Confirm availability status as distribution channels may list obsolete or limited-stock items.

Selection Notes

Select this component when a 400MHz capable synthesizer with five outputs is required for PCIe or SATA links. Ensure the design accommodates the 28-SSOP footprint and the 3.135V–3.465V power supply requirement. Verify that the HCSL output swing meets the receiver input thresholds of the target devices.

Part Context

This part belongs to the 9FG104 family of clock synthesizers from Renesas. It serves as a specialized timing solution for high-speed serial interfaces. Related variants in the family may offer different output counts, frequencies, or package types, such as the 9FG104EGLFT which utilizes a TSSOP package.
