950812CGLFT

Application Specific Clock/Timing Overview

The Renesas 950812CGLFT is a CPU clock generator and frequency multiplexer IC housed in a 56-TFSOP package. It features an integrated PLL and accepts crystal inputs to generate up to 24 differential clock outputs from a single circuit, achieving a 1:24 input-to-output ratio. The device operates at frequencies up to 200MHz with a supply voltage range of 3.135V to 3.465V. Designed for high-performance computing applications, it supports a commercial operating temperature range of 0°C to 90°C.

Application Specific Clock/Timing Feature Summary

• Generates 24 differential clock outputs from a single crystal input using a 1:24 ratio
• Integrated Phase-Locked Loop (PLL) for precise frequency synthesis
• Maximum output frequency of 200MHz for high-speed CPU timing
• Operates within a 3.135V to 3.465V supply voltage range

Application Specific Clock/Timing Applications

Application Specific Clock/Timing Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer, with discontinuance notices recorded in November 2015. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement alternatives, as standard manufacturing has ceased.

Application Specific Clock/Timing Selection Notes

Select this part for designs requiring a single-input, multi-output differential clock solution for Intel CPUs. Ensure the design accommodates the 56-TFSOP surface-mount package dimensions and the specific 3.135V-3.465V power rail requirements. Verify that the 200MHz maximum frequency meets the target processor's timing specifications.

Application Specific Clock/Timing Part Context

The 950812CGLFT belongs to the ICS950812C family of clock generators. It serves as a specialized timing solution for complex motherboard architectures where multiple synchronized clock domains are required for central processing units and associated chipset components.

Application Specific Clock/Timing Replacement Considerations

Due to the EOL status, verify compatibility with newer Renesas timing controllers or equivalent multi-output clock generators from other manufacturers that support similar pinouts and electrical characteristics.
