ICS9154A-27CS16

Overview

The ICS9154A-27CS16 is a frequency generator integrated circuit designed for Intel CPU server applications. It operates with a crystal input and provides a single clock output circuit. The device supports an input-to-output ratio of 1:05 and achieves a maximum frequency of 140MHz. It does not feature differential inputs or outputs. The unit functions within a supply voltage range of 2.97V to 5.5V and is rated for an operating temperature between 0°C and 70°C. It is housed in a 16-SOIC package with a width of 3.90mm, suitable for surface mount installation.

Procurement Notes

Verify the specific suffix '27C' against official Renesas documentation to confirm exact electrical tolerances and packaging variations. Ensure the 16-SOIC footprint matches the target PCB design. Confirm that the 140MHz maximum frequency meets system requirements. Check for RoHS compliance status if required by local regulations. Validate the operating temperature range suitability for the intended deployment environment.

Selection Notes

Select this component when a dedicated frequency generator for Intel CPU servers is required. The 1:05 input-to-output ratio must align with the system's clock distribution needs. Consider the 140MHz limit relative to other available generators. The absence of differential signaling may influence board layout choices compared to LVDS alternatives. Ensure the 16-SOIC package size fits the mechanical constraints of the assembly.

Part Context

This part belongs to the Application Specific Clock/Timing category from Renesas Electronics Corporation. It serves as a specialized solution for server infrastructure rather than a general-purpose oscillator. The designation indicates a fixed-function generator optimized for specific processor architectures.
