9FG104EFLF

Overview

The Renesas 9FG104EFLF is a clock synthesizer and jitter cleaner designed for PCI Express Gen2 applications. It features four HCSL outputs with a maximum frequency of 400 MHz, driven by a crystal input up to 27.5 MHz. The device operates on a 3.135 V to 3.465 V supply within a commercial temperature range of 0°C to +70°C. Packaged in a 28-SSOP format, it integrates PLL circuitry to generate precise clock signals for high-speed digital interfaces.

Feature Summary

• Four-output HCSL clock generation optimized for PCIe Gen2 architectures
• Maximum output frequency capability of 400 MHz
• Crystal input interface supporting frequencies up to 27.5 MHz
• Integrated PLL for low-jitter signal synthesis

Applications

• PCI Express Gen2 system clocking
• Intel CPU server platforms
• SATA interface timing

Procurement Notes

Verify the package designation carefully, as the 'EFLF' suffix typically indicates a 28-SSOP housing, which differs from the TSSOP variant found in similar model numbers like 9FG104EGLF. Confirm RoHS compliance status through official documentation before integration. Ensure the specific revision matches design requirements.

Selection Notes

Select this component when four differential HCSL outputs are required for PCIe Gen2 designs. Compare against the 9FG104EGLF if a TSSOP package is preferred or if an extended industrial temperature range (-40°C to +85°C) is necessary. Verify that the 28-SSOP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the 9FG104 family of clock synthesizers manufactured by Renesas Electronics (formerly Integrated Circuit Systems). These devices are engineered to provide stable clocking solutions for high-performance computing and storage systems requiring strict jitter specifications.

Replacement Considerations

The ICS9FG104EGLFT serves as a functional alternative offering identical electrical performance but housed in a 28-TSSOP package. For designs requiring wider temperature tolerance, the 9FG104EFILFT provides an industrial grade option.
