9UMS9633BKILF

Overview

The Renesas Electronics Corporation 9UMS9633BKILF is a clock generator and support product designed for Ultra Mobile PC (UMPC) applications. It operates with a supply voltage range of 1.425V to 3.465V and supports a maximum frequency of 166.67MHz. The device features an internal PLL, crystal input, and single-ended clock output. Packaged in a 48-VFQFPN (6x6mm) with an exposed pad, it includes one circuit with a 1:9 input-to-output ratio. The component supports differential inputs/outputs and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the manufacturer as Renesas Electronics Corporation or IDT, as ownership transitions occurred. Confirm the package type is 48-VFQFPN with a 6x6 mm footprint. Ensure the industrial temperature grade (-40°C to +85°C) matches system requirements. Check RoHS compliance status against current regulatory standards.

Selection Notes

Select this component for UMPC designs requiring low-power differential push-pull pairs for CPU, SRC, LCD, and DOT clocks. Verify that the 1.5V VDD IO operation and 3.3V VDD core supplies align with the target platform's power rails. Ensure the SMBus interface compatibility exists for configuration registers.

Part Context

This part belongs to the ICS9UMS9633 family of ultra-mobile PC clocks. It is specifically engineered for Poulsbo-based architectures. The device integrates multiple clock generators into a single chip to reduce board space and component count in mobile devices.
