25QHM572C1.0-22.1184

Oscillators Overview

The 25QHM572C1.0-22.1184 is a QuikXO spread spectrum crystal oscillator (SSXO) manufactured by Mercury United Electronics, Inc. It operates at a center frequency of 22.1184 MHz with a frequency tolerance of ±1.0%. The device utilizes CMOS output levels and supports a supply voltage range including 2.5V. It features an Enable/Disable function for power management. The component is housed in a compact 4-pad ceramic SMD package measuring 7.0 x 5.0 x 1.4 mm. It is designed to reduce system-level electromagnetic interference (EMI) through center or down-spread spectrum modulation.

Oscillators Feature Summary

• Reduces system-level electromagnetic interference (EMI) by approximately 20 dB
• Supports direct replacement for traditional crystal oscillators without PCB layout redesign
• Features center spread or down-spread spectrum modulation capabilities

Oscillators Applications

• Electronics requiring low EMI signal generation
• Systems needing direct substitution for standard crystal oscillators
• Compact electronic devices utilizing small form-factor oscillators

Oscillators Procurement Notes

Verify the specific ordering suffix and voltage requirements against the official datasheet before procurement. Confirm that the 2.5V enable/disable functionality aligns with the target system's logic levels. Ensure the 4-pad ceramic SMD package dimensions fit the designated footprint on the printed circuit board. Check for RoHS compliance status if required by project specifications.

Oscillators Selection Notes

Select this component when EMI reduction is critical and space constraints require a small surface-mount package. The CMOS output interface suits digital logic circuits operating at compatible voltage levels. The enable/disable feature provides additional power control flexibility compared to standard continuous-operation oscillators. Consider the ±1.0% tolerance for applications requiring moderate frequency stability.
