ICS950902DGLF

Overview

The ICS950902DGLF is a PC main clock integrated circuit manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply voltage and is designed for application-specific clock timing functions within personal computer architectures. The device features clock outputs and does not include an internal Phase-Locked Loop (PLL). It is housed in a 56-TFSOP package with a width of 6.10mm, also referred to as a 56-TSSOP supplier device package. The component supports surface mount installation and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• PC main clock IC providing dedicated timing signals for system components
• Operates at a standard 3.3V supply voltage
• Available in a 56-pin TFSOP/TSSOP surface-mount package
• Designed for commercial temperature ranges (0°C to 70°C)

Applications

• Personal Computer (PC) motherboard clock distribution
• System timing for legacy Intel chipset platforms

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability requires checking distributor stock status directly, as new production units are no longer manufactured. Buyers should confirm end-of-life status and lead times with authorized suppliers before procurement planning.

Selection Notes

Select this part only if the design specifically requires a non-PLL PC main clock generator in a 56-pin TFSOP package. Ensure the system architecture supports 3.3V logic levels and operates within the 0°C to 70°C commercial temperature range. Verify pin compatibility with existing PCB layouts due to the specific 56-TSSOP footprint.

Part Context

The ICS950902DGLF belongs to the ICS950902 series of application-specific clock generators. These devices were historically used to provide essential clock signals for desktop and embedded PC systems, replacing discrete oscillator solutions with integrated timing management.

Replacement Considerations

As the ICS950902DGLF is discontinued, engineers must evaluate alternative clock generators from current Renesas portfolios or other manufacturers that offer compatible pinouts, voltage levels, and output frequencies for PC chipset applications.
