9VRS4451AKILFT

Overview

The 9VRS4451AKILFT is an application-specific clock and timing integrated circuit manufactured by Renesas Electronics Corporation. It is designed primarily for PCI Express (PCIe) applications. The device features a Phase-Locked Loop (PLL) and operates within a supply voltage range of 1.05V to 1.5V. It supports a maximum frequency of 200MHz and utilizes a crystal input. The component is housed in a 48-VFQFN exposed pad package, specifically identified as a 48-VFQFPN (6x6) supplier device package. It is rated for operation over an industrial temperature range of -40°C to 85°C. The part status is listed as obsolete.

Feature Summary

• Designed for PCI Express (PCIe) specific timing requirements
• Integrates a Phase-Locked Loop (PLL) for clock generation
• Supports high-frequency operation up to 200MHz

Applications

• PCI Express (PCIe) systems
• Intel Atomic platform implementations

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is limited to existing stock or surplus channels; new production orders are not accepted. Verify authenticity through authorized distributors and check for Product Change Notices (PCNs) regarding assembly site changes or label modifications prior to procurement.

Selection Notes

Engineers should consider this part only for legacy designs requiring PCIe timing at 200MHz with low-voltage operation. Due to its obsolete status, alternative solutions must be evaluated for long-term supply stability. Ensure the design accommodates the specific 48-VFQFN package dimensions and thermal requirements defined in the datasheet.

Part Context

The 9VRS4451AKILFT belongs to the 9VRS4451 family of clock generators from Renesas. It serves as a specialized timing solution for high-speed serial interfaces like PCIe. The 'AKILFT' suffix typically denotes specific packaging and environmental compliance attributes, such as RoHS3 compliance and tape-and-reel delivery format.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the part is obsolete, cross-reference with current Renesas timing IC portfolios or third-party equivalents is required for design updates.
