3QHM572D0.25-56.000

Oscillators Overview

The 3QHM572D0.25-56.000 is a QuikXO spread spectrum crystal oscillator manufactured by Mercury United Electronics, Inc. It operates at a frequency of 56.000 MHz with a CMOS output signal and a down-spread modulation profile of -0.25%. The device functions on a 3.3V supply voltage and features an enable/disable control pin for power management. It is housed in a compact 4-pad ceramic surface-mount package measuring 7.0 x 5.0 x 1.4 mm. The component is RoHS compliant and lead-free.

Oscillators Feature Summary

• Integrated EMI reduction via spread spectrum technology
• Low electromagnetic interference design for sensitive applications
• Built-in enable and disable functionality for power optimization

Oscillators Applications

• High-speed digital circuits requiring low noise clock sources
• Telecommunications equipment minimizing spectral emissions
• Consumer electronics with strict EMI compliance requirements

Oscillators Procurement Notes

Verify the manufacturer designation carefully, as listings may reference Mercury Electronics Ind. Co. Ltd or Mercury United Electronics, Inc. Ensure the part number suffix matches the specific frequency and modulation parameters. Confirm RoHS compliance status through official documentation before procurement to meet environmental standards.

Oscillators Selection Notes

Select this component when a 56 MHz clock source with reduced EMI is required. The CMOS output level suits standard logic interfaces. Consider the 3.3V operating voltage and the physical dimensions of the 7.0x5.0mm package against board space constraints. The enable pin allows for dynamic power control during idle states.

Oscillators Part Context

This oscillator belongs to the QuikXO series designed for applications demanding low electromagnetic interference. The spread spectrum technique modulates the frequency slightly to reduce peak harmonic energy. This specific model provides a stable 56 MHz reference while maintaining a small footprint suitable for dense PCB layouts.

Oscillators Replacement Considerations

Direct substitutes include other models from the same QuikXO family with identical frequency and package dimensions but different modulation profiles. Cross-referencing datasheets is necessary to ensure compatible output voltage levels and enable pin configurations.
