9UMS9633BFILF

Overview

The Renesas 9UMS9633BFILF is a clock generator IC designed for Ultra Mobile PC (UMPC) applications. It features an integrated PLL and crystal oscillator, supporting input frequencies up to 166.67MHz with a 1:9 output ratio. The device operates on a supply voltage range of 1.425V to 3.465V and supports an industrial temperature range of -40°C to +85°C. It provides multiple low-power differential push-pull outputs for CPU, SRC, LCD, and DOT clocks, along with a single-ended REF output.

Feature Summary

• Supports ULV CPUs with CPU outputs ranging from 67 to 167 MHz
• Includes dedicated TEST/SEL and TEST/MODE pins to save isolation resistors
• Features a CPU STOP# input for power management control
• Contains fully integrated voltage regulator and series resistors on differential outputs

Applications

• Poulsbo Based Ultra-Mobile PC (UMPC)
• Industrial Temperature Range UMPC systems

Procurement Notes

Verify the component status as the related part number 9UMS9633BFILFT is marked as End-of-Life (EOL). Confirm availability through authorized distributors or check for alternative packaging types if direct procurement is restricted due to discontinuation notices.

Selection Notes

Select this component for designs requiring industrial temperature compliance (-40°C to +85°C). Ensure the system utilizes 1.5V VDD IO operation and 3.3V VDD core supplies. Verify that the application benefits from the integrated series resistors on differential outputs, which eliminates the need for external components.
