9VRS4338DKLFT

Overview

The Renesas 9VRS4338DKLFT is an application-specific clock timing integrated circuit designed for Intel Atomic and PCI Express (PCIe) systems. It operates with a maximum frequency of 200MHz and utilizes an internal Phase-Locked Loop (PLL). The device supports differential outputs while accepting non-differential inputs. It functions within a supply voltage range of 1.05V to 1.5V and is rated for commercial operating temperatures between 0°C and 70°C. The component is housed in a 48-VFQFPN package with dimensions of 6x6 mm, featuring an exposed pad for surface mount installation.

Feature Summary

• Integrated PLL for precise clock generation targeting Intel Atomic and PCIe applications
• Maximum output frequency of 200MHz with differential signaling capability
• Low voltage operation ranging from 1.05V to 1.5V
• Compact 48-VFQFPN (6x6mm) surface-mount package

Applications

• Intel Atomic platform clock distribution
• PCI Express (PCIe) system timing
• General purpose clock generation for specific timing requirements

Procurement Notes

This component is classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability should focus on the recommended replacement part number 9VRS4420DKLFT. Standard packaging quantities and lead times are not applicable due to the end-of-life status. Buyers must confirm current stock levels through authorized distributors or surplus suppliers before procurement.

Selection Notes

Designers requiring this specific timing solution should evaluate the manufacturer-recommended substitute, 9VRS4420DKLFT, as the original part is discontinued. Selection criteria should prioritize compatibility with Intel Atomic and PCIe architectures. Ensure that the replacement part meets the required 200MHz frequency and 1.05V-1.5V supply voltage specifications. Verify that the 48-VFQFPN footprint remains compatible with existing board layouts if pinout equivalence is confirmed.

Part Context

The 9VRS4338DKLFT belongs to Renesas' portfolio of application-specific clock generators optimized for high-speed digital interfaces. It addresses the timing needs of Intel's Atom processor ecosystem and PCIe interconnects. As an obsolete component, it has been succeeded by newer generations such as the 9VRS4420 series, which offer updated features while maintaining functional compatibility for legacy designs.

Replacement Considerations

The manufacturer recommends 9VRS4420DKLFT as the direct replacement. This substitute maintains similar functionality for Intel Atomic and PCIe applications. Engineers should verify electrical parameter alignment and package compatibility during the transition from the obsolete 9VRS4338DKLFT.
