Oscillators Procurement Notes

Verify the specific operating voltage and output logic compatibility with your target circuit design before procurement. Ensure that the 1.8V supply requirement aligns with your system's power rails. Confirm that the enable pin configuration matches your control scheme. Check the physical footprint requirements against your PCB layout to ensure the 4-SMD package fits correctly. Validate the frequency specification against your application needs.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable/disable control feature. The small 2.0x1.6 mm package makes it suitable for space-constrained designs. Consider the LVCMOS output level compatibility with downstream digital logic. Evaluate the need for a standard XO versus other oscillator types based on phase noise and stability requirements for the specific application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and voltage options. The suffix OE typically denotes the enable function. Similar parts in the series include different frequencies like 21.2 MHz or 50.256 MHz, maintaining the same package and logic type but varying in electrical specifications.

Oscillators Replacement Considerations

Direct substitutes may include other 39.2385 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6mm package with 1.8V operation and enable pins. Verify pinout compatibility and electrical parameters such as load capacitance and drive strength before substitution.
