9VRS4338DKLFT-INT

Overview

The 9VRS4338DKLFT-INT is an Intel Atomic and PCI Express (PCIe) clock timing integrated circuit manufactured by Renesas Electronics Corporation. It operates with a maximum frequency of 200MHz and supports differential outputs. The device is housed in a 48-VFQFPN package measuring 6x6 mm with an exposed pad, designed for surface mount installation. It functions within a supply voltage range of 1.05V to 1.5V and is rated for an operating temperature range of -40°C to 85°C. This component is classified as obsolete and no longer in production.

Feature Summary

• Designed specifically for Intel Atomic and PCI Express (PCIe) applications
• Maximum output frequency of 200MHz with PLL capability
• Differential output signaling configuration
• Compact 48-VFQFPN (6x6) surface-mount package

Applications

• Intel Atomic platform clock generation
• PCI Express (PCIe) system timing
• Server and workstation motherboard designs requiring PCIe Gen 1-3 compliance

Procurement Notes

This part number is officially obsolete and has been discontinued by the manufacturer. Sourcing is limited to existing stock from distributors or secondary markets. Verification of authenticity is critical due to potential availability of refurbished units. Buyers should confirm the specific revision and lot date code before purchase, as lead times vary significantly across suppliers.

Selection Notes

Engineers replacing this component should consider the manufacturer-recommended substitute, 9VRS4420DKLFT. The replacement offers similar functionality but requires verification of pin compatibility and software configuration registers. Designers must ensure that the new component meets the specific jitter and power requirements of the original Intel Atomic or PCIe design constraints.

Part Context

The 9VRS4338 series belongs to Renesas' portfolio of high-performance clock generators targeting server and storage infrastructure. These devices are engineered to provide low-jitter clock signals essential for high-speed data transmission standards like PCIe. The DK suffix typically indicates a specific packaging and environmental qualification variant within the broader product family.

Replacement Considerations

The manufacturer recommends the 9VRS4420DKLFT as a direct replacement. Users should verify electrical parameter compatibility and check for any necessary firmware updates or register reprogramming when migrating to the newer model.
