9VRS4338DKILF

Overview

The Renesas 9VRS4338DKILF is an application-specific clock and timing integrated circuit designed for Intel Atomic™ and PCI Express (PCIe) systems. It operates with a maximum frequency of 200MHz and features an internal Phase-Locked Loop (PLL). The device supports differential outputs while lacking differential inputs. It functions within a supply voltage range of 1.05V to 1.5V and is rated for an operating temperature between -40°C and 85°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 clock generation
• Differential output capability
• Optimized for Intel Atomic™ and PCIe applications
• Low voltage operation (1.05V ~ 1.5V)

Applications

• Intel Atomic™ platforms
• PCI Express (PCIe) systems

Procurement Notes

Verify the part status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm that the 48-VFQFPN package dimensions match the design footprint requirements. Ensure the 1.05V to 1.5V supply voltage range aligns with the target system power rails. Check for moisture sensitivity level (MSL) constraints during storage and handling.

Selection Notes

Select this component when designing for Intel Atomic™ or PCIe architectures requiring a 200MHz clock source. The differential output feature is suitable for noise-sensitive signal paths. Verify compatibility with the 1.05V to 1.5V power domain. The 48-VFQFPN package size of 6x6 mm should be evaluated against available board space constraints.

Part Context

This component belongs to the Renesas application-specific clock and timing family. It is distinct from general-purpose oscillators by its specific optimization for Intel Atomic™ and PCIe standards. The inclusion of an internal PLL allows for jitter reduction and frequency synthesis without external resonators.

Replacement Considerations

Public documentation indicates the 9VRS4420DKLFT as a manufacturer-recommended replacement. Verify pinout compatibility and electrical parameter alignment before substitution.
