9EMS9633BKILFT

Overview

The 9EMS9633BKILFT is a clock distribution IC designed for Ultra Mobile PC (UMPC) applications. It features a single input and nine outputs with a 1:9 ratio. The device operates at a maximum frequency of 166.67MHz and includes an integrated Phase-Locked Loop (PLL). It supports crystal inputs and provides differential push-pull clock outputs. The supply voltage range is 1.425V to 3.465V, and it functions within a temperature range of -40°C to 85°C. The component is housed in a 48-VFQFN package.

Feature Summary

• Integrates low power differential push-pull pairs for CPU, SRC, LCD, and DOT signals
• Includes dedicated TEST/SEL and TEST/MODE pins to save isolation resistors
• Features a fully integrated voltage regulator and series resistors on differential outputs
• Supports Dothan ULV CPUs with specific CPU STOP# input for power management

Applications

• Poulsbo Based Ultra-Mobile PC (UMPC)
• Embedded Applications
• Dothan ULV CPU Clock Distribution

Procurement Notes

Verify the exact suffix and manufacturer part number against official Renesas documentation to ensure compatibility. Confirm current availability status as components may be discontinued or subject to product change notices. Check moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the selected package variant matches the design requirements.

Selection Notes

Select this component for UMPC designs requiring specific clock distribution for CPU, SRC, and display interfaces. Consider the 48-VFQFN package for space-constrained layouts. Verify that the 1.425V to 3.465V supply range aligns with system power rails. Ensure the integrated PLL and output configurations meet the timing requirements of the target processor architecture.

Part Context

This part belongs to the 9UMS/9EMS series of clock generators and distributors by Renesas. It is specifically tailored for mobile and ultra-mobile computing platforms. The series typically integrates multiple clock outputs with low-power differential signaling to support complex system-on-chip architectures common in portable devices.

Replacement Considerations

Check for direct substitutes within the 9UMS9633 family, such as the 9UMS9633BFILFT or 9UMS9633BKILFT, ensuring package and pinout compatibility. Verify if alternative Renesas clock distributors offer similar output ratios and voltage ranges.
