ICS953201BFLF

Overview

The ICS953201BFLF is a Timing Control Hub™ (TCH™) integrated circuit manufactured by Renesas Electronics Corporation. Designed for PCI Express (PCIe) applications, this device functions as a PC system clock generator. It operates on a single 3.3V supply voltage and supports an industrial temperature range from 0°C to +70°C. The component is housed in a 56-BSSOP surface-mount package with a width of 7.50mm. This specific part number does not include an internal Phase-Locked Loop (PLL).

Feature Summary

• Timing Control Hub™ architecture optimized for PCI Express timing control.
• Fixed 3.3V power supply operation.
• Industrial operating temperature range: 0°C to +70°C.
• 56-lead BSSOP surface-mount package.

Applications

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

Procurement Notes

The ICS953201BFLF is listed as a discontinued product. Verification of availability requires checking current distributor inventory or authorized secondary market sources. Ensure the 56-SSOP package dimensions match the target PCB footprint before procurement.

Selection Notes

Select this component when a fixed-function PCIe clock generator without an internal PLL is required. Verify that the 3.3V supply voltage aligns with the system design. The absence of a PLL limits frequency synthesis flexibility compared to programmable alternatives.

Part Context

This device belongs to the TCH™ series of application-specific clock generators. It is distinct from other Renesas clock products such as the ICS9DB803DFLF buffer or the ICS932S200BFLFT server clock generator due to its specific PCIe focus and lack of internal PLL capabilities.

Replacement Considerations

As the product is discontinued, verify pin compatibility with alternative PCIe clock generators. Check if replacement parts require external PLL components or different supply voltages.
