ICS9UMS9633AKLFT

Overview

The ICS9UMS9633AKLFT is an ultra-mobile PC (UMPC) fanout buffer clock generator manufactured by Renesas Electronics Corporation. It operates with a single crystal input and provides one output channel at a maximum frequency of 166.67MHz. The device supports a supply voltage range of 1.425V to 3.465V and includes an integrated PLL. Designed for surface mount installation, it is housed in a 48-VFQFN package with exposed pads, specifically sized as a 48-VFQFPN (6x6mm). The component is rated for industrial operating temperatures between -40°C and 85°C.

Feature Summary

• Ultra Mobile PC (UMPC) dedicated fanout buffer design
• Integrated Phase-Locked Loop (PLL) for clock generation
• Single crystal input supporting up to 166.67MHz output frequency
• Industrial temperature range operation from -40°C to 85°C

Applications

• Ultra Mobile PC (UMPC) main clock distribution
• Portable computing systems requiring low-power clock buffering
• Embedded applications utilizing crystal-based timing references

Procurement Notes

Verify the specific suffix 'AKLFT' against official Renesas documentation to confirm exact packaging quantity and tape-and-reel specifications. Confirm current availability status as related models in this series may have discontinuation notices. Ensure compatibility with existing board layouts using the 48-VFQFPN (6x6) footprint before procurement.

Selection Notes

Select this component when a dedicated fanout buffer for UMPC architectures is required. It is suitable for designs needing a single high-speed clock output derived from a crystal source within the 166.67MHz limit. Verify that the system power supply falls within the 1.425V to 3.465V range and that the 48-pin QFN package fits the mechanical constraints.

Part Context

This part belongs to the ICS9UMS9633 series of clock generators optimized for ultra-mobile PCs. It functions primarily as a distribution buffer to drive multiple loads from a single reference. The series typically integrates voltage regulators and differential output drivers to support various subsystems within compact mobile devices.

Replacement Considerations

Check for direct pin-to-pin replacements within the same ICS9UMS9633 family. Verify if variants with different suffixes offer identical electrical characteristics and package dimensions. Consult manufacturer obsolescence notices for potential end-of-life status.
