ICS9169M-01T

Overview

The ICS9169M-01T is a clock and frequency generator IC manufactured by Renesas Electronics Corporation, designed primarily for Intel CPU server applications. It features a single circuit with a 1:14 input-to-output ratio, generating up to 14 outputs from one reference. The device accepts clock or crystal inputs and provides CMOS clock outputs without differential signaling. Operating on a 3V to 5.5V supply, it supports frequencies up to 100MHz within an industrial temperature range of 0°C to 70°C. Packaged in a 28-SOIC surface-mount case, this component integrates PLL functionality for precise timing generation.

Feature Summary

• Generates multiple clock outputs with a 1:14 input-to-output ratio
• Supports both clock and crystal input sources
• Operates within a 3V to 5.5V voltage supply range
• Maximized frequency output of 100MHz

Applications

• Intel CPU Server systems
• Application-specific clock and timing circuits
• Frequency generation for processor boards

Procurement Notes

This product is officially listed as obsolete by the manufacturer. Verification should confirm current availability through secondary markets or authorized distributors handling end-of-life inventory. Check RoHS compliance status, as the source indicates non-compliance. Ensure the 28-SOIC package dimensions match the target PCB footprint before procurement.

Selection Notes

Select this component when designing for Intel CPU server architectures requiring a single-reference multi-output clock solution. Verify that the 100MHz maximum frequency meets system requirements. The absence of differential outputs necessitates checking signal integrity constraints for long traces. Confirm power supply stability within the 3V to 5.5V range to ensure proper PLL operation.

Part Context

The ICS9169 series belongs to Renesas' portfolio of application-specific clock generators. This specific model targets high-volume server platforms where cost-effective, fixed-ratio clock distribution is required. It replaces discrete oscillator solutions by integrating the PLL and buffer stages into a single 28-pin package, simplifying board layout for multi-core processor designs.

Replacement Considerations

As the part is obsolete, verify pin compatibility with potential alternatives. Check if newer Renesas clock generators offer similar 1:14 ratios and 100MHz capabilities. Ensure replacement packages match the 28-SOIC form factor or require adapter solutions.
