IMIZ9953AA

Overview

The IMIZ9953AA is a PLL-based clock distribution device manufactured by Cypress Semiconductor Corp. It operates as a multi-output zero delay buffer designed for 3.3V applications with support for frequencies up to 180MHz. The component features an integrated Phase-Locked Loop (PLL) to minimize output jitter and skew, ensuring precise timing alignment between input and output clocks. It supports 110MHz clock signals and includes specific compatibility for PowerPC architectures, making it suitable for high-speed digital systems requiring reliable clock distribution.

Feature Summary

• Integrates a Phase-Locked Loop (PLL) for low-jitter clock generation
• Functions as a multi-output zero delay buffer
• Supports 110MHz clock frequencies
• Compatible with PowerPC architecture requirements

Applications

• Clock distribution in PowerPC-based systems
• High-speed digital circuit timing synchronization
• Multi-output clock buffering for data communication interfaces

Procurement Notes

Verify the manufacturer designation as Cypress Semiconductor Corp or its successor Infineon Technologies, noting that Cypress was acquired. Confirm the package type and pinout configuration against official datasheets before integration. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Cross-reference the full part number including suffixes to guarantee electrical specifications match your design requirements exactly.

Selection Notes

Select this component when designing systems requiring precise clock alignment with minimal propagation delay. It is appropriate for applications needing multiple synchronized clock outputs derived from a single source. Consider the 3.3V operating voltage and 180MHz maximum frequency limits during system planning. Evaluate the specific PowerPC compatibility if targeting embedded processor designs that rely on strict timing constraints for bus operations.

Part Context

This device belongs to the family of PLL-based clock distribution components used in complex digital electronics. It addresses the need for clean, stable clock signals in high-performance computing and communication equipment. The zero-delay buffer functionality distinguishes it from simple buffers by actively adjusting phase to eliminate latency between input and output edges.

Replacement Considerations

Check for direct substitutes within the same product line or compatible families from Infineon Technologies, which acquired Cypress Semiconductor. Verify equivalent electrical characteristics such as supply voltage, frequency range, and output drive strength before substitution.
