ICS951412BGLF

Overview

The ICS951412BGLF is a system clock generator designed for AMD CPU and PCI Express (PCIe) applications. It features a single circuit with a 1:16 input-to-output ratio, accepting crystal inputs to generate up to 229.43MHz output frequencies. The device operates on a 3.135V to 3.465V supply within a 0°C to 70°C temperature range. Packaged in a 56-TSSOP surface-mount case, it integrates PLL functionality to provide precise clock signals for high-speed digital systems without differential signaling requirements.

Feature Summary

• Integrated PLL for stable clock generation
• 1:16 frequency ratio for PCIe and AMD CPU architectures
• Crystal input interface
• Single-ended outputs

Applications

• AMD CPU system clocking
• PCI Express (PCIe) bus timing
• High-speed digital system synchronization

Procurement Notes

Verify the package designation matches the 56-TSSOP form factor. Confirm the voltage supply range aligns with the 3.135V to 3.465V specification. Ensure the operating temperature range of 0°C to 70°C meets the environmental requirements of the target application.

Selection Notes

Select this component when a 1:16 clock division is required for AMD or PCIe platforms. Ensure the design supports crystal input configurations. Verify that single-ended outputs are sufficient for the trace lengths and noise immunity requirements of the PCB layout.

Part Context

This part belongs to Renesas' Application Specific Clock/Timing category. It serves as a dedicated solution for generating reference clocks in computing and peripheral interfaces, specifically targeting legacy or specific AMD and PCIe implementations requiring fixed ratio multiplication/division.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas family that offer extended temperature ranges or updated packaging options. Verify electrical compatibility regarding supply voltage and output drive strength before substitution.
