9LPRS436CGILF

Overview

The Renesas 9LPRS436CGILF 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 166.67MHz from a crystal input. The device operates on a 3.135V to 3.465V supply within a -40°C to 85°C temperature range. Packaged in a 48-TFSOP surface-mount case, it provides differential outputs without differential input.

Feature Summary

• Designed specifically for Intel Atom CPU and PCIe timing requirements
• Generates 14 output clocks from a single crystal input at frequencies up to 166.67MHz
• Operates within a standard industrial temperature range of -40°C to 85°C

Applications

• Intel Atom-based desktop and notebook platforms
• PCI Express interface clock generation
• System board timing solutions for embedded computing

Procurement Notes

Verify the specific suffix 'GILF' against manufacturer documentation to confirm package and tape-and-reel specifications. Confirm current availability status as this component family may have end-of-life notifications or alternative packaging options available from distributors.

Selection Notes

Select this part when a fixed-ratio 1:14 frequency synthesis solution is required for Atom processors. Ensure the design supports a crystal input rather than a CMOS oscillator. Verify that the 48-TSSOP footprint matches the PCB layout constraints.

Part Context

This component belongs to the Renesas 9LPRS436 series of specialized clock generators. These devices are engineered to meet the strict jitter and skew requirements of high-speed serial interfaces like PCIe while supporting the multi-clock demands of system-on-chip architectures.

Replacement Considerations

Check for updated suffixes such as 'CGLFT' which may indicate different packaging or lifecycle status. Consult official substitution guides for pin-compatible alternatives if the specific 'GILF' variant is discontinued.
