Oscillators Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure correct output logic and voltage specifications. Confirm that the required operating temperature range aligns with your application environment. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the selected variant matches the specific frequency tolerance requirements of your design.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS compatibility is required. Consider the small 2.0x1.6mm footprint for dense PCB layouts. Evaluate the need for enable/disable control versus always-on operation based on power constraints. Verify that the 22.5792 MHz frequency meets the specific data rate or processing clock needs of the target system.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO series, which offers various frequencies and packages. The 18QHTF21 series typically targets cost-sensitive applications requiring reliable timing. Similar parts in this family may differ in frequency, voltage, or package size while maintaining the same basic operational principles and output characteristics.

Oscillators Replacement Considerations

Direct substitutes include other 22.5792 MHz LVCMOS oscillators in 4-SMD no-lead packages from compatible manufacturers. Ensure replacement parts match the 1.8V supply requirement and physical dimensions. Verify that any alternative component maintains similar frequency stability and load capacitance specifications.
