Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official documentation to confirm the enable/disable feature and voltage level. Ensure the operating temperature range meets system requirements. Cross-reference the part number with the latest datasheet from Mercury Electronics to validate pinout and electrical specifications before integration.

Oscillators Selection Notes

Select this component when a 1.8V supply and LVCMOS output are required. The small 2.0x1.6 mm footprint makes it suitable for dense PCB layouts. Consider the enable/disable capability if power conservation during idle states is necessary. Confirm that the 26.660 MHz frequency aligns with the target system's clocking architecture.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 4-SMD package. The series supports multiple voltage options and output types. The 'OE' suffix typically denotes specific operational characteristics defined by the manufacturer, distinguishing it from other variants in the same physical form factor.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical frequency and package, such as 18QHTF21-26.660-PD, provided the output logic and voltage levels match. Verify functional equivalence through official cross-reference lists.
