Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application needs before procurement. Ensure that the 1.8V supply voltage aligns with the target system's power rails. Confirm the operating temperature range meets the environmental conditions of the end product. Cross-reference the package dimensions with the PCB footprint to ensure mechanical compatibility during assembly.

Oscillators Selection Notes

Select this oscillator when a 44.0055 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the need for enable/disable functionality. Evaluate the 2.0x1.6mm package size against available board space. Compare performance metrics such as phase noise and stability against alternative solutions if high-precision timing is critical for the specific application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes a specific ordering or packaging variant within the manufacturer's catalog.
