25QHM572C2.0-68.000

Oscillators Overview

The 25QHM572C2.0-68.000 is a QuikXO spread spectrum crystal oscillator (SSXO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a center frequency of 68.000 MHz with a CMOS output signal. The device features low electromagnetic interference (EMI) characteristics achieved through center spread modulation with a deviation of ±2.0%. It functions on a single 2.5V supply voltage and includes an enable/disable control pin for power management. The component is housed in a compact 4-pad ceramic surface-mount package measuring 7.0 x 5.0 x 1.4 mm, suitable for space-constrained electronic designs.

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 2.5V supply voltage aligns with your system's power architecture. Confirm that the enable/disable pin functionality is utilized correctly to manage power states. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate the physical footprint dimensions against your PCB layout constraints.

Oscillators Selection Notes

Select this component when low EMI is critical for signal integrity in high-frequency applications. The CMOS output simplifies interfacing with standard logic families without additional buffering. Consider the enable feature if dynamic power management is required for battery-operated devices. The 68 MHz frequency is suitable for various bus standards. Evaluate the small form factor against available board space limitations.

Oscillators Part Context

This oscillator belongs to the QuikXO series from Mercury United Electronics, designed for general-purpose clocking needs. The SSXO variant specifically targets EMI reduction in sensitive digital environments. It serves as a replacement for traditional fixed-frequency crystals where noise suppression is necessary. The family offers various frequencies within the same package outline.

Oscillators Replacement Considerations

Direct substitutes must match the 68 MHz frequency, CMOS output type, and 2.5V operating voltage. Verify that alternative components support center spread modulation with similar deviation percentages. Ensure the replacement fits the 7.0x5.0x1.4mm 4-pad ceramic package. Cross-reference pinouts for the enable function to maintain circuit compatibility.
