9VRS4420DKLF

Overview

The Renesas 9VRS4420DKLF is a dedicated clock generator designed for PCI Express (PCIe) applications. It operates within an industrial temperature range of -40°C to +85°C and utilizes a Phase-Locked Loop (PLL) architecture. The device supports a maximum frequency of 122.88MHz and is housed in a 48-VFQFPN package with dimensions of 6x6 mm and an exposed pad. This component serves as a timing solution for PCIe systems, providing precise clock signals required for high-speed data transmission interfaces.

Procurement Notes

Verify the exact ordering suffix against manufacturer documentation, as variations such as DKLFT may indicate specific packaging or tape-and-reel configurations. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with the target system's voltage requirements and thermal constraints during procurement planning.

Selection Notes

Select this component when designing for PCIe architectures requiring a dedicated clock source. Verify that the 122.88MHz maximum frequency meets the system's bandwidth needs. Consider the 48-VFQFPN package size for board space constraints. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the final application.

Part Context

This part belongs to Renesas' Application Specific Clock/Timing category. It is distinct from general-purpose oscillators by its optimization for PCIe standards. The 48-lead VFQFPN package allows for dense PCB layouts. It functions as a critical timing element in digital systems requiring synchronized clock distribution.
