ICS9250BF-12LFT

Overview

The ICS9250BF-12LFT is a clock/frequency generator IC designed for Intel CPU server applications. It features a single circuit with a crystal input and clock output, operating at a maximum frequency of 133MHz. The device provides a 1:24 input-to-output ratio without differential signaling. It functions within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range of 0°C to 70°C. The component utilizes a Phase-Locked Loop (PLL) and is housed in a 56-BSSOP surface-mount package.

Procurement Notes

Verify the specific suffix 'LFT' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm current availability as this product line may have end-of-life or last-time-buy statuses. Ensure compatibility with existing board layouts requiring a 56-SSOP footprint.

Selection Notes

Select this component when designing for Intel CPU servers requiring a 133MHz clock generation capability. Ensure the design accommodates the 3.135V to 3.465V supply voltage range. Verify that the 0°C to 70°C commercial temperature range meets the system's environmental requirements. Confirm that a crystal input source is available for the PLL operation.

Part Context

This part belongs to the ICS9250 series of clock generators manufactured by Renesas Electronics Corporation. The series is tailored for high-performance computing environments, specifically targeting Intel architecture servers. The 56-SSOP package allows for compact integration into dense server motherboards.

Replacement Considerations

Consult Renesas official substitution guides for compatible alternatives. Verify pinout compatibility if replacing with other members of the ICS9250 family.
