952601EGLF

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 952601EGLF is a Timing Control Hub (TCH) clock and frequency synthesizer IC designed for Intel CPU applications. It operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 400MHz. The device features a single circuit with a 1:23 input-to-output ratio, utilizing a Phase-Locked Loop (PLL). It accepts a crystal input and provides differential clock outputs. The component is housed in a 56-TSSOP package and is rated for an operating temperature range of 0°C to 70°C.

Application Specific Clock/Timing Feature Summary

• System clock generation for processors using TCH architecture

Application Specific Clock/Timing Procurement Notes

The 952601EGLF is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus market sources. Ensure compliance with RoHS3 specifications and check for any Product Change Notices (PCN) regarding marking or packaging updates prior to procurement.

Application Specific Clock/Timing Selection Notes

Select this component only if the design specifically requires a Renesas TCH-compatible clock generator for Intel CPUs. Verify that the 56-TSSOP package footprint matches the PCB layout. Confirm that the 400MHz maximum frequency and 1:23 ratio meet the system's timing requirements. Note that the device is discontinued; consider alternative timing solutions if long-term supply stability is required.

Application Specific Clock/Timing Part Context

The 952601EGLF belongs to the IDT/Renesas TCH™ series of clock generators. It is functionally related to variants such as the 952601EFLF, differing primarily in packaging (TSSOP vs SSOP) and reel/tape configuration. These devices were widely used in server and workstation platforms requiring precise clock distribution for Intel processors.

Application Specific Clock/Timing Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific TCH programming interface and legacy status. Review Renesas application notes for modern clock generator alternatives compatible with Intel architectures. Verify electrical compatibility including voltage levels and output drive strength before substituting.
