Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 3.3V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm package dimensions. Check for any specific handling instructions regarding ESD sensitivity during installation.

Oscillators Selection Notes

Select this model when a 14.432 MHz clock signal is required with LVCMOS compatibility. Consider the 3.3V operating voltage constraint. Evaluate the need for power-down capability if battery life is critical. Compare package size constraints against alternative oscillator types. Verify temperature range specifications for the intended operating environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6mm SMD package. The series typically supports both 1.8V and 3.3V options, with the PD suffix indicating power-down functionality. It serves as a drop-in replacement for other oscillators in similar footprints requiring comparable electrical characteristics.

Oscillators Replacement Considerations

Direct substitutes may include other 14.432 MHz XO components in 2.0x1.6mm packages with LVCMOS outputs and 3.3V operation. Verify pinout compatibility and electrical parameters such as jitter and phase noise. Cross-reference with manufacturer cross-reference lists for validated alternatives.
