• Consumer electronics with timing requirements

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage level. Ensure the operating temperature range and load capacitance requirements match the target circuit design before procurement. Cross-reference the part number with the manufacturer's latest datasheet to avoid confusion with similar variants like the 25QHT series.

Oscillators Selection Notes

Select this component when a 1.8V supply is available and an enable pin is required for power control. Compare stability specifications such as ppm against system jitter requirements. Consider the 4-SMD no-lead package dimensions for PCB layout constraints relative to other oscillators in the QHTF family.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 18QHTF21 variant specifically denotes the 1.8V supply version within this lineup, distinguishing it from higher voltage counterparts like the 25QHTF21.

Oscillators Replacement Considerations

Direct substitutes may include other 18.5625 MHz LVCMOS oscillators with enable features from different manufacturers, provided they match the 4-SMD footprint and 1.8V supply requirements. Verify pin compatibility and electrical characteristics carefully.
