ISL55191IBZ

Overview

The ISL55191IBZ is a high-speed, single-input to four-output clock buffer belonging to the Renesas ClockBlocks family. It functions as a low-cost distribution device for synchronizing clock signals across multiple loads. The component supports high-frequency operation with low skew characteristics, ensuring precise timing alignment in digital systems. It is designed for applications requiring reliable clock distribution from a single source to four distinct destinations without introducing significant phase errors.

Feature Summary

• Single input to four output configuration for efficient clock distribution
• Low cost design within the ClockBlocks family
• High-speed operation capabilities for digital synchronization

Applications

• Digital system clock distribution
• Synchronization of multiple logic components
• High-speed data acquisition systems

Procurement Notes

Verify the manufacturer designation carefully, as the model number is associated with Renesas Technology Corp. and its subsidiaries following historical acquisitions. Confirm the specific suffix 'IBZ' matches the required package and temperature grade against current official datasheets. Ensure compatibility with existing board layouts and signal integrity requirements before procurement.

Selection Notes

Select this component when a low-cost, four-channel clock buffer is required for distributing a single clock signal. Consider alternatives like the 552-02B if a dual-output monolithic version is preferred. Evaluate power supply voltage ranges and load capacitance requirements to ensure stable operation at the desired frequency.

Part Context

This part is part of the broader ClockBlocks family, which includes various clock buffers and delay lines. It serves as a solution for systems needing to fan out a clock signal to multiple synchronous devices. The family emphasizes cost-effectiveness and small form factors for embedded applications.

Replacement Considerations

The 552-02B is a related monolithic dual version within the same family. Verify pinout compatibility and electrical specifications against current Renesas documentation before substitution.
