952601EFLF

Application Specific Clock/Timing Overview

The Renesas Electronics 952601EFLF is a Timing Control Hub (TCH) clock generator 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 one input channel and provides 23 outputs with a 1:23 input-to-output ratio. It utilizes a crystal input and generates clock outputs via an internal PLL. The component is housed in a 56-lead SSOP package (7.50mm width) and functions within an operating temperature range of 0°C to 70°C.

Application Specific Clock/Timing Feature Summary

• Timing Control Hub (TCH) architecture optimized for Intel CPU timing control
• Maximum output frequency capability of 400MHz
• Single crystal input supporting 23 differential clock outputs
• Integrated Phase-Locked Loop (PLL) for frequency synthesis

Application Specific Clock/Timing Applications

• Intel CPU system clock generation
• PC motherboard main clock distribution
• High-performance computing platform timing control

Application Specific Clock/Timing Procurement Notes

The 952601EFLF is officially designated as End-of-Life (EOL) by the manufacturer, with a discontinuation notice dated May 7, 2019. Availability is restricted, and sourcing requires verification of remaining stock or qualified second-source alternatives. Buyers must confirm RoHS3 compliance and Moisture Sensitivity Level (MSL) Class 3 status prior to procurement.

Application Specific Clock/Timing Selection Notes

This component is specific to legacy Intel chipset architectures requiring a 56-pin SSOP form factor. Designers should verify that the 3.3V nominal supply tolerance (3.135V–3.465V) matches the target system power rails. Due to the EOL status, alternative selection should prioritize newer TCH series devices or compatible clock generators with equivalent pin counts and output configurations.

Application Specific Clock/Timing Part Context

The 952601EFLF belongs to the Renesas (formerly IDT) 952601 series of clock generators. It is functionally related to other TCH family members such as the 952926 but is distinctively configured for Intel CPU platforms. The part number alias ICS952601EFLF reflects its historical manufacturing lineage under Integrated Circuit Specialties.

Application Specific Clock/Timing Replacement Considerations

As an obsolete component, direct replacements are limited. Evaluation of newer Renesas TCH series devices or generic high-frequency clock generators with matching 56-SSOP packages is required. Compatibility depends on verifying output drive strength, jitter specifications, and I2C programmability if dynamic adjustment is needed.
