952601EFLFT

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 952601EFLFT is a clock generator and frequency synthesizer IC designed for Intel CPU Timing Control Hub applications. It operates with a maximum frequency of 400MHz and features a single output circuit. The device utilizes a Phase-Locked Loop (PLL) architecture and accepts crystal inputs to generate precise clock signals. It is housed in a 56-BSSOP package with a width of 7.50mm. The component requires a supply voltage ranging from 3.135V to 3.465V and functions within an operating temperature range of 0°C to 70°C. It has a moisture sensitivity level of 3 (168 hours).

Application Specific Clock/Timing Procurement Notes

This component is officially listed as obsolete by the manufacturer, with an End-of-Life notification dated May 7, 2019. Availability is restricted, and it may not be sold in all regions through standard distributors. Verification of current stock status and alternative sourcing channels is required before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this part only if compatibility with legacy Intel CPU Timing Control Hub architectures is mandatory. Ensure the design supports the 3.135V–3.465V supply voltage range and the 56-SSOP footprint. Consider that the device is obsolete; verify long-term availability or plan for redesign if future production continuity is required.

Application Specific Clock/Timing Part Context

The 952601EFLFT belongs to the 952601 series of clock generators. It is functionally similar to the 952601EFLF variant, differing primarily in packaging format (Reel/Cut Tape vs. Tube). Both variants share identical electrical specifications and are designated for Intel CPU timing control applications.

Application Specific Clock/Timing Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be evaluated based on pin compatibility and electrical equivalence with other Renesas TCH™ series components.
