ICS953202BFT

Overview

The ICS953202BFT is a Timing Control Hub (TCH) system clock generator manufactured by Renesas Electronics Corporation. Designed for PCI Express and PC applications, this integrated circuit operates on a single 3.3V supply voltage. It provides multiple clock outputs within the 56-BSSOP surface-mount package. The device functions without an internal Phase-Locked Loop (PLL). It supports an operating temperature range from 0°C to 70°C, ensuring reliable performance in standard commercial environments.

Feature Summary

• Timing Control Hub (TCH) architecture optimized for PCI Express systems
• Single 3.3V power supply operation
• No internal PLL required for basic clock generation
• Available in 56-lead BSSOP surface-mount package

Applications

• PCI Express (PCIe) system clock generation
• PC motherboard timing control
• System clock distribution hubs

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as historical data indicates non-compliance for some variants. Check manufacturing date codes against obsolescence notices. Ensure the 'BFT' suffix matches the specific reel or tube packaging requirements of the procurement channel. Validate pinout compatibility with existing PCB footprints.

Selection Notes

Select this component when designing PCI Express interfaces requiring TCH functionality without complex PLL programming. Ensure the design environment stays within the 0°C to 70°C operating temperature range. Verify that the 56-BSSOP package dimensions fit the mechanical constraints. Confirm that the 3.3V supply rail is stable and meets the current requirements for all clock outputs simultaneously.

Part Context

This part belongs to the ICS953202 series, which are specialized clock generators for AMD-K8 based platforms. The 'BFT' suffix typically denotes the tape-and-reel packaging variant of the standard 'BF' tube version. Both share identical electrical characteristics and pinouts, differing only in shipping and handling logistics for automated assembly lines.

Replacement Considerations

Direct replacements may be limited due to the specific TCH configuration. Verify pin-to-pin compatibility with any alternative clock generators. Ensure the substitute supports the same PCIe timing specifications and output drive strengths. Check if the new component requires external components that were previously integrated or handled internally by the ICS953202.
