9LPRS436CGLF

Overview

The Renesas 9LPRS436CGLF 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 166.67MHz from a crystal input. The device operates on a 3.135V to 3.465V supply within a 0°C to 85°C temperature range. Packaged in a 48-TFSOP surface-mount case, it provides differential outputs while maintaining a non-differential input configuration.

Feature Summary

• Designed specifically for ATOM CPU and PCIe timing requirements
• Generates 14 differential clock outputs from a single crystal input
• Maximum operating frequency of 166.67MHz
• Operates on a 3.3V nominal supply voltage

Applications

• ATOM-based desktop and notebook platforms
• PCI Express interface clock generation
• System timing for Intel Atom processors

Procurement Notes

Verify the specific suffix 'GLF' against the manufacturer's current documentation to confirm RoHS compliance and package dimensions. Confirm availability status as this component may be subject to end-of-life notices or replacement by newer series variants.

Selection Notes

Select this component when a fixed-frequency synthesizer for Intel Atom architecture is required. Ensure the design supports a crystal input rather than a CMOS oscillator. Verify that the 48-pin TSSOP footprint matches the PCB layout constraints.

Part Context

This part belongs to the 9LPRS436 family of clock generators. It serves as a specialized timing solution for legacy Intel Atom processor systems, providing the necessary multi-phase clocks for system buses and peripheral interfaces.

Replacement Considerations

Check for updated Renesas datasheets for potential pin-compatible replacements or next-generation clock synthesizers if this unit is discontinued.
