9UMS9633BFILFT

Overview

The Renesas 9UMS9633BFILFT is a clock distribution IC designed for Ultra Mobile PC (UMPC) applications, operating within an industrial temperature range of -40°C to +85°C. It features a single circuit with a 1:9 input-to-output ratio, driven by a crystal input at 14.318MHz. The device supports CPU outputs ranging from 67 to 166.67MHz and includes integrated spread spectrum capabilities. Power supply requirements are specified as 1.425V to 3.465V for the I/O section and 3.3V for the core and reference sections. The component is housed in a 48-BSSOP package.

Feature Summary

• Supports ULV CPUs with CPU outputs configurable between 67 MHz and 167 MHz via FSL inputs.
• Includes dedicated TEST/SEL and TEST/MODE pins to eliminate external isolation resistors.
• Features a CPU STOP# input for power management control.
• Integrates a voltage regulator and series resistors on differential outputs.

Applications

• Poulsbo Based Ultra-Mobile PC (UMPC) systems
• Industrial temperature range computing platforms

Procurement Notes

Verify component status before procurement as the part is marked as End-of-Life (EOL). Confirm availability through authorized distributors or secondary markets. Check for alternative packaging options if standard reel quantities are unavailable. Ensure compliance with RoHS3 specifications for environmental standards.

Selection Notes

Select this component for UMPC designs requiring industrial temperature operation (-40°C to +85°C). Ensure the design accommodates the specific 1.5V IO and 3.3V Core/REF power domains. Verify that the 48-SSOP package dimensions fit the PCB layout constraints. Consider the integrated series resistors when designing trace impedance matching.

Part Context

This part belongs to the IDT/ICS Ultra Mobile PC Clock family, specifically tailored for Poulsbo-based architectures. It serves as a central clock generator for CPU, SRC, LCD, and DOT signals in mobile computing devices. The 'BI' suffix indicates the industrial temperature grade variant.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is listed as EOL, consult the manufacturer's official obsolescence notices for potential recommended replacements or last-time buy information.
