ICS950220AFLF

Overview

The ICS950220AFLF is a Timing Control Hub™ clock generator and multiplexer IC designed for Intel CPU applications. Manufactured by Renesas Electronics Corporation, it operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 200MHz. The device features a single circuit with a 1:19 input-to-output ratio, utilizing a crystal input and providing differential clock outputs. It is housed in a 48-BSSOP package (7.50mm width) and functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated PLL-based clock generation optimized for Intel CPU Timing Control Hub architectures
• Supports 200MHz maximum output frequency with a fixed 1:19 input-to-output ratio
• Differential clock output capability with crystal input interface
• Surface-mount 48-SSOP packaging for compact board integration

Applications

• Intel CPU timing control hub implementations
• System clock distribution for processor platforms
• Frequency generation for server and workstation motherboards

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distributor stock. Confirm the specific revision level and lot date code when sourcing from non-primary channels to ensure compatibility with existing design specifications.

Selection Notes

Select this part only if the design requires a 1:19 ratio and 200MHz limit compatible with legacy Intel CPU timing hubs. Verify that the 48-SSOP footprint matches the PCB layout. Since the device is obsolete, evaluate pin-compatible or functionally equivalent successors from the same TCH series family for new production runs.

Part Context

The ICS950220AFLF belongs to the TCH™ series of clock generators specifically engineered for Intel platform requirements. It serves as a critical timing element in systems requiring precise frequency synthesis for processor buses. The 'LF' suffix indicates lead-free compliance, aligning with environmental standards prevalent during its active production lifecycle.

Replacement Considerations

As the ICS950220AFLF is discontinued, consult the manufacturer's product change notification (PCN) dated January 15, 2013, for potential cross-references or end-of-life guidance. No specific substitute part numbers are publicly confirmed in the provided documentation.
