5991ZQ-QS5991-2JRC

Overview

The Quality Semiconductor 5991ZQ-QS5991-2JRC is a programmable skew PLL clock driver. It functions as a clock buffer and driver within the timing component category. The device integrates a phase-locked loop to manage clock signal distribution with adjustable skew characteristics. This specific part number represents a military-grade or high-reliability variant of the QS5991 series, designed for applications requiring precise timing control and robust performance in demanding environments.

Feature Summary

• Integrates a phase-locked loop for stable clock generation
• Provides programmable output skew capabilities
• Functions as a dedicated clock buffer and driver

Applications

• High-performance digital systems requiring precise clock alignment
• Military and aerospace electronic assemblies
• Complex logic circuits needing low-skew clock distribution

Procurement Notes

Verify that the procurement source provides valid documentation confirming the ZQ suffix indicates the required environmental rating. Ensure the supplier can provide traceability records consistent with the specified military or high-reliability grade. Confirm that the package type matches the design requirements before finalizing the order.

Selection Notes

Select this component when the application demands a single-chip solution for generating and distributing clock signals with controlled skew. Consider the QS5991 series if the system requires a PLL-based driver rather than a simple buffer. Evaluate the specific ZQ suffix requirements against the operational environment constraints to ensure compatibility.

Part Context

This part belongs to the QS5991 family of programmable skew PLL clock drivers produced by Quality Semiconductor. The series is known for providing flexible clock routing solutions. The 5991ZQ-QS5991-2JRC designation specifies the particular grade and package configuration within this lineup, distinguishing it from commercial variants like the standard QS5991-2JRC.

Replacement Considerations

Direct substitutes include other parts from the QS5991 family such as the QS5991-2JRC, provided the environmental and packaging specifications align with the system requirements. Verify pinout and functional equivalence before substitution.
