ICS953202BF

Overview

The ICS953202BF is a Timing Control Hub™ (TCH) clock generator manufactured by Renesas Electronics Corporation. Designed for PCI Express (PCIe) applications, this integrated circuit provides precise timing signals without an internal Phase-Locked Loop (PLL). It operates on a single 3.3V supply voltage and supports surface-mount installation in a 56-BSSOP package with a width of 7.50mm. The device functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Timing Control Hub™ architecture optimized for PCI Express systems
• No internal PLL; generates clock outputs directly
• Single 3.3V power supply operation
• 56-lead BSSOP surface-mount package

Applications

• PCI Express (PCIe) system clock generation
• AMD-K8 platform timing control
• PC motherboard clock distribution

Procurement Notes

The ICS953202BF is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or Last Time Buy status. Compliance data indicates the component does not meet RoHS standards. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component only if the design specifically requires a TCH-based clock solution for PCIe or AMD-K8 architectures without PLL integration. Verify that the 56-BSSOP package fits the board layout constraints. Confirm that the 0°C to 70°C operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the TCH™ series from Renesas, focusing on specific timing control hubs rather than general-purpose oscillators. It is distinct from other Renesas clock ICs that may include PLLs or support different interface standards like USB or SATA. The 56-pin form factor is characteristic of complex clock generators for multi-lane bus systems.

Replacement Considerations

As the product is obsolete, direct replacements must be sourced from distributor cross-reference lists. Verify pinout compatibility and electrical specifications with any alternative components. No official substitute part numbers are confirmed in the provided documentation.
