Oscillators Procurement Notes

Verify the specific order suffix to ensure the correct supply voltage and package variant are selected. Confirm that the 1.8V operating requirement aligns with the target circuit design. Check manufacturer documentation for detailed electrical characteristics and thermal specifications before integration.

Oscillators Selection Notes

Choose this component when a 14.05 MHz frequency is required with LVCMOS outputs. Ensure the PCB layout accommodates the 2.0x1.6mm footprint. Verify that the 1.8V supply rail is stable and meets the current consumption requirements specified in the datasheet.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and voltages. The 'PD' suffix typically indicates the inclusion of a power-down pin or feature. Similar parts in the series include different frequency options like 15.700 MHz or 96.768 MHz within the same physical package.

Oscillators Replacement Considerations

Direct substitutes may include other 14.05 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson or SiTime, provided pinout and voltage compatibility are verified. Cross-reference with Mercury's own variants like 18QHTF21-14.050-OE if lead-free or specific packaging differences are required.
