Oscillators Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm pinout and electrical characteristics. Ensure the required frequency tolerance and temperature range align with system requirements before procurement. Cross-reference the package outline drawing to confirm mechanical fit on the PCB layout.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small footprint. Consider the ±50ppm stability specification against system jitter requirements. Evaluate the enable/disable feature necessity for power-sensitive designs compared to continuous-operation alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series of high-frequency crystal oscillators from Mercury Electronics. The series typically includes various frequencies such as 19.687 MHz and 49.680 MHz. These components are designed for general-purpose timing applications in portable and industrial devices.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with matching 1.8V supply and LVCMOS outputs, provided the frequency difference is acceptable for the application.
