9LPRS436CKILF

Overview

The Renesas 9LPRS436CKILF is a dedicated clock synthesizer designed for Intel 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 maximum frequencies of 166.67MHz. Packaged in a 48-VFQFN exposed pad (6x6mm), it functions reliably across an industrial temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix 'CKI' against official Renesas documentation to confirm pinout compatibility and electrical specifications. Ensure the 48-VFQFN footprint matches the target PCB design. Confirm RoHS compliance status and check for any End-of-Life notices or alternative part recommendations directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring precise timing for Intel Atom processors and PCIe lanes. Verify that the required output frequency does not exceed 166.67MHz and that the system power supply remains stable between 3.135V and 3.465V. Ensure the operating environment stays within the specified -40°C to +85°C range for reliable performance.

Part Context

This device belongs to the 9LPRS436 series of specialized clock generators. It serves as a critical timing solution for legacy and current Intel Atom-based architectures, providing the necessary multi-phase clocks for system synchronization. The 48-pin form factor allows for dense board layouts in space-constrained mobile and desktop applications.

Replacement Considerations

Consult the official Renesas replacement matrix for verified cross-references. Check for updated suffixes indicating package variations or environmental certifications. Do not substitute with generic clock generators without verifying PCIe signal integrity requirements.
