ICS950902DFLF

Overview

The ICS950902DFLF is a PC main clock integrated circuit manufactured by Renesas Electronics Corporation. It operates on a 3.3V supply voltage and supports surface mount installation in a 56-BSSOP package with a width of 7.50mm. The device functions as an application-specific clock generator without an internal PLL. It is designed for use in personal computer systems, providing stable clock signals within an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated PC main clock generator IC
• Operates at 3.3V supply voltage
• Available in 56-BSSOP (7.50mm width) surface mount package
• No internal Phase-Locked Loop (PLL)

Applications

• Personal computer main clock generation

Procurement Notes

Verify the exact part number suffix against official Renesas documentation, as 'DFLF' may indicate specific packaging or revision details not fully detailed in general summaries. Confirm availability status, as similar variants like ICS950902DGLF have been marked as obsolete in public records. Ensure the 56-SSOP package matches the design requirements.

Selection Notes

Select this component for legacy PC motherboard designs requiring a dedicated main clock source. Verify that the 3.3V logic level compatibility aligns with the system's power rails. The absence of an internal PLL suggests it may be used in conjunction with other timing components or for fixed-frequency applications where external loop filtering is unnecessary.

Part Context

This component belongs to Renesas' portfolio of application-specific clock and timing devices. It is distinct from general-purpose oscillators or programmable clock generators due to its fixed function for PC main clocks. The 56-pin SSOP package allows for compact integration into dense PCB layouts typical of computer motherboards.

Replacement Considerations

Check for direct pin-to-pin replacements in the ICS9509xx series. Verify if newer generations offer improved jitter performance or lower power consumption while maintaining the same 56-SSOP footprint and 3.3V operation.
