Oscillators Procurement Notes

Verify the specific ordering suffix and manufacturing date code when sourcing this component, as availability may vary across distributors. Confirm that the received units match the exact model number 25QHM572C1.0-27.142 to ensure correct frequency and tolerance specifications. Check for any regional compliance markings such as RoHS status on the packaging or documentation provided by the supplier.

Oscillators Selection Notes

Select this oscillator when low EMI emission is critical for system compliance. The center spread feature helps reduce peak noise energy. Ensure the host circuit supports the required CMOS voltage levels and has access to the enable pin if power management is needed. Verify that the 7.0x5.0mm footprint fits the PCB layout constraints.

Oscillators Part Context

This part belongs to the 25QHM series of spread spectrum oscillators from Mercury Electronics. These components are engineered to provide stable clock signals while minimizing radiated emissions through frequency dithering. The series offers various frequencies and packages to suit different embedded design requirements.

Oscillators Replacement Considerations

Direct substitutes must match the 27.142 MHz frequency, ±1.0% tolerance, CMOS output, and 7.0x5.0mm SMD package. Verify that alternative sources offer identical spread spectrum characteristics and enable functionality.
