9UMS9610CKLFT

Overview

The Renesas 9UMS9610CKLFT is a distribution UMPC fanout buffer IC designed for ultra-mobile PC applications. It features one circuit with a 1:9 input-to-output ratio, operating at a maximum frequency of 200MHz. The device accepts a crystal input and provides clock outputs. It operates within a supply voltage range of 1.425V to 3.465V and supports an operating temperature range of 0°C to 70°C. The component is housed in a 48-VFQFN package with an exposed pad, specifically identified as a 48-VFQFPN (6x6) supplier device package.

Feature Summary

• Integrated PLL for clock generation
• 1:9 Input/Output Ratio
• Crystal Input Interface
• Surface Mount Package

Applications

• Ultra Mobile PC (UMPC) systems

Procurement Notes

The 9UMS9610CKLFT is listed as obsolete by the manufacturer. Availability is limited to existing stock or last-time buys. Verify end-of-life status and lead times with distributors before design-in. RoHS3 compliant and MSL level 3.

Selection Notes

Select this component for low-power clock distribution in UMPC designs requiring a single crystal input and nine differential outputs. Ensure the 1.425V-3.465V supply range matches system power rails. The 48-VFQFN package requires appropriate PCB thermal management for the exposed pad.

Part Context

This part belongs to the 9UMS9610 series of clock generators and buffers optimized for mobile computing platforms. It serves as a fanout buffer to distribute reference clocks to multiple subsystems while maintaining signal integrity and power efficiency in portable devices.

Replacement Considerations

As the part is obsolete, check for direct pin-compatible replacements from Renesas or equivalent fanout buffers with similar 1:9 ratios and VFQFN packages. Verify electrical compatibility including voltage ranges and output drive capabilities.
