ICS9UMS9633AKLF

Overview

The ICS9UMS9633AKLF is a clock generator and support product designed for Ultra Mobile PC (UMPC) applications. Manufactured by Renesas Electronics Corporation, this integrated circuit features a single circuit with a 1:9 input-to-output ratio. It accepts a crystal input and provides differential clock outputs. The device supports a maximum frequency of 166.67MHz and operates within a supply voltage range of 1.425V to 3.465V. It includes an internal PLL and is housed in a 48-VFQFPN package with dimensions of 6x6 mm. The component is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Designed specifically for Ultra Mobile PC (UMPC) main clock generation
• Integrates a Phase-Locked Loop (PLL) for clock synthesis
• Provides 1:9 fan-out distribution from crystal input to differential clock outputs
• Operates on a wide supply voltage range of 1.425V to 3.465V

Applications

• Ultra Mobile PC (UMPC) systems
• Mobile Internet Device (MID) platforms
• Low-power portable computing hardware

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm any distinct electrical or mechanical variations compared to standard variants like the BKILFT. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement. Ensure the 48-VFQFPN exposed pad footprint matches the target PCB layout requirements.

Selection Notes

Select this component when designing UMPC architectures requiring a dedicated low-power main clock source. The 166.67MHz maximum frequency and 1:9 output ratio suit systems needing multiple synchronized clock domains from a single crystal reference. Verify that the 1.425V minimum supply voltage aligns with the system's power management strategy.

Part Context

This part belongs to the 9UMS9633 series of clock generators optimized for mobile computing. It serves as a primary clock distribution solution for Intel Atom-based platforms commonly found in UMPCs. The series typically integrates voltage regulators and offers low-power differential push-pull pairs for CPU and memory interfaces.

Replacement Considerations

The 9UMS9633BKILFT is a documented variant within the same family. Verify pinout compatibility and electrical parameter equivalence before substitution. Other members of the 9UMS9633 series may offer different frequency ranges or packaging options.
