9LPRS436CKLFT

Overview

The Renesas 9LPRS436CKLFT is a dedicated clock synthesizer designed for ATOM CPU and PCI Express (PCIe) applications. It features a single circuit with a 1:14 input-to-output ratio, generating up to 14 differential clock outputs from a crystal input. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 166.67MHz. Packaged in a 48-VFQFPN (6x6mm) surface-mount case with an exposed pad, it functions reliably across an operating temperature range of 0°C to 85°C.

Feature Summary

• Supports ATOM CPU and PCIe architectures
• Generates 14 differential clock outputs from one crystal input
• Maximum frequency of 166.67MHz
• Operates on 3.135V to 3.465V supply

Applications

• ATOM CPU systems
• PCI Express (PCIe) platforms

Procurement Notes

Verify the package designation matches the 48-VFQFPN (6x6mm) specification. Confirm the operating temperature range is suitable for the intended environment, as this variant covers 0°C to 85°C. Ensure the design accommodates the required 3.135V to 3.465V power supply rails for proper functionality.

Selection Notes

Select this component when designing for Intel ATOM processors or PCIe interfaces requiring a single-input, multi-output clock solution. The 48-VFQFPN package is appropriate for space-constrained surface-mount designs. Verify that the system requires differential outputs and can support the specified 166.67MHz maximum frequency limit.

Part Context

This part belongs to the 9LPRS436 series of clock synthesizers. While other variants like the 9LPRS436CGLFT exist in different packages such as TSSOP, the CKLFT suffix specifically denotes the 48-VFQFPN package. These devices are engineered to provide stable timing signals for high-speed digital logic in computing and communication hardware.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series if the current part is unavailable. Ensure any substitute maintains the 48-VFQFPN package and meets the 166.67MHz frequency requirement.
