9UMS9610CKLF

Overview

The Renesas 9UMS9610CKLF is a clock distribution buffer designed for Ultra Mobile PC (UMPC) applications. It features a single circuit with a 1:9 input-to-output ratio, converting a crystal input into nine HCSL clock outputs. The device operates within a supply voltage range of 1.425V to 3.465V and supports maximum frequencies up to 200MHz. It integrates an internal PLL and is housed in a 48-VFQFPN package with exposed pads, measuring 6x6 mm. The component functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• 1:9 fan-out ratio for distributing a single crystal reference to multiple loads
• Integrated PLL for clock generation and distribution
• HCSL output type optimized for low power and noise immunity
• Compact 48-VFQFPN (6x6 mm) surface-mount package

Applications

• Ultra Mobile PC (UMPC) system clock distribution
• Portable computing devices requiring low-power clocking
• Embedded systems needing crystal-to-multiple-clock conversion

Procurement Notes

Verify the RoHS compliance status and Moisture Sensitivity Level (MSL 3) before integration. Confirm that the 48-VFQFPN footprint matches the PCB layout design. Check for any End-of-Life (EOL) notices or Production Change Notices (PCN) affecting availability or material composition.

Selection Notes

Select this component when a single crystal oscillator needs to drive nine distinct clock inputs in a UMPC architecture. Ensure the design accommodates the 1.425V to 3.465V supply range and the specific thermal requirements of the 0°C to +70°C operating environment.

Part Context

This part belongs to the Renesas clock timing portfolio, specifically tailored for mobile computing form factors. It serves as a dedicated distribution solution for UMPC platforms, replacing discrete buffering solutions with an integrated PLL-based IC to save board space and reduce component count.

Replacement Considerations
