ICS9154A-27CS16T

Overview

The ICS9154A-27CS16T is a single-circuit frequency generator designed for Intel CPU server applications. It accepts a crystal input and provides five clock outputs with a 1:5 ratio. The device operates without an internal PLL, supporting frequencies up to 140MHz. It functions within a supply voltage range of 2.97V to 5.5V and is rated for commercial temperatures from 0°C to 70°C. Housed in a 16-SOIC package (3.90mm width), it lacks differential signaling capabilities.

Feature Summary

• Single circuit frequency generator with 1:5 input-to-output ratio
• Crystal input interface for clock generation
• Supports output frequencies up to 140MHz
• Operates on 2.97V to 5.5V supply voltage

Applications

• Intel CPU servers
• System clock distribution
• Server motherboard timing

Procurement Notes

Verify the specific suffix '27CS16T' against official Renesas documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure compatibility with existing crystal oscillator specifications before integration into server designs.

Selection Notes

Select this component when a fixed-frequency generator for Intel CPU servers is required without PLL complexity. Confirm that the 140MHz maximum frequency meets system requirements and that the 16-SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the Renesas frequency generator family tailored for server infrastructure. It serves as a dedicated clock source for processor subsystems, replacing discrete logic solutions with a single integrated circuit for improved reliability and space efficiency.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible alternatives or updated generations within the same product line. Verify if newer revisions offer enhanced performance or extended temperature ranges while maintaining server compatibility.
