Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable pin configuration matches your control logic. Check the operating temperature range specifications to ensure suitability for your environmental conditions. Validate the package footprint against your PCB layout guidelines.

Oscillators Selection Notes

Select this component when a precise 124.957186 MHz clock signal is required with low voltage operation. Consider the LVCMOS output compatibility with your downstream digital logic. Evaluate the enable/disable feature if power management is critical. Compare the 2.0x1.6mm package size against available board space. Assess the need for standard XO performance versus more advanced jitter specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small SMD package. The series typically supports 1.8V operation and LVCMOS outputs. Other variants in this family include different frequencies such as 44.2 MHz or 8.3 MHz, maintaining similar physical and electrical characteristics while differing in output frequency.

Oscillators Replacement Considerations

Direct replacements must match the 124.957186 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that any substitute component offers equivalent enable/disable functionality and similar phase noise characteristics. Cross-reference with other manufacturers offering standard XO oscillators in this form factor.
