9UMS9633BKLFT

Overview

The Renesas Electronics Corporation 9UMS9633BKLFT is a clock generator and support product designed for Ultra Mobile PC (UMPC) and Mobile Internet Device applications. It operates with a single crystal input and provides one circuit of clock outputs. The device supports a maximum frequency of 166.67MHz with a 1:9 input-to-output ratio. It functions within a supply voltage range of 1.425V to 3.465V and is rated for an operating temperature range of -40°C to +85°C. The component is housed in a 48-VFQFPN package with dimensions of 6x6 mm.

Feature Summary

• Designed specifically for Ultra Mobile PC (UMPC) main clock generation
• Supports frequencies up to 166.67MHz with a 1:9 output ratio
• Operates on a single crystal input with integrated PLL
• Available in a compact 48-VFQFPN (6x6 mm) surface-mount package

Applications

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

Procurement Notes

Verify the manufacturer designation, as some sources list Integrated Device Technology (IDT) while others specify Renesas Electronics Corporation due to corporate acquisition history. Confirm the specific suffix 'BKLFT' matches the required RoHS compliance and lead-free status. Check current availability status, as related variants may be marked as obsolete or last-time buy depending on the distributor inventory.

Selection Notes

Select this component when designing for UMPC architectures requiring a dedicated low-power main clock source. Ensure the design accommodates the 1.425V to 3.465V supply voltage range. Verify that the system requires a 1:9 fan-out ratio from a single crystal input. The 48-VFQFPN package requires appropriate PCB footprint design for the exposed pad thermal dissipation.

Part Context

This part belongs to the 9UMS9633 series of clock generators. It is functionally similar to the 9UMS9633BKILFT variant, which shares the same core specifications but may differ in packaging or ordering suffix details. The series is targeted at mobile computing platforms needing efficient clock distribution.

Replacement Considerations

Direct substitutes include other parts from the 9UMS9633 family, such as the 9UMS9633BKILFT. Verify pin compatibility and electrical parameters before substitution. No other cross-model replacements are confirmed in public documentation.
