9FGL0441CKILFT

Overview

The 9FGL0441CKILFT is a PCI Express (PCIe) clock generator IC manufactured by Renesas Electronics Corporation. It features an integrated Phase-Locked Loop (PLL) and provides one output channel with a maximum frequency of 100MHz. The device operates on a supply voltage ranging from 3.135V to 3.465V and supports differential outputs using HCSL or LVCMOS signaling standards. Designed for surface mount installation, it is housed in a 24-VFQFN package with exposed pad dimensions of 4x4mm. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated PLL-based PCIe clock generation
• Maximum output frequency of 100MHz
• Supply voltage range of 3.135V to 3.465V
• Housed in a compact 24-VFQFN (4x4mm) package

Applications

• PCI Express (PCIe) clock distribution systems
• High-speed digital interface timing circuits

Procurement Notes

This component is identified as discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than standard retail channels. Ensure that any sourced units are verified for authenticity and storage history due to the end-of-life status.

Selection Notes

Engineers replacing this part should consider the 9FGL0451CKILFT, which shares similar electrical characteristics including a 100MHz frequency and 3.3V operation but utilizes a 24-QFN package. Selection must account for the specific pinout compatibility and package footprint differences between the original and potential substitutes.

Part Context

The 9FGL0441CKILFT belongs to the 9FGL04xx series of low-power, low-voltage PCIe clock generators. This family is designed to meet strict jitter requirements for PCIe Gen 1 through Gen 6 applications. The 'C' suffix typically denotes the commercial temperature grade, while 'KILFT' indicates the specific tape-and-reel packaging configuration.
