Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the exact enable/disable configuration and tolerance specifications. Ensure the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD footprint dimensions with PCB layout guidelines to guarantee mechanical compatibility.

Oscillators Selection Notes

Select this model when a 38.912 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. The enable/disable feature allows for dynamic power management. Consider the 4-SMD package size for assembly constraints and ensure the operating temperature range meets the environmental requirements of the final application.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and package types. Similar models like the 18QHTF21-6.912-OE share the same package and logic type but differ in frequency. The series is characterized by standard performance levels and surface mount construction, catering to mass production needs in the quartz oscillator market.

Oscillators Replacement Considerations

Direct substitutes include other 38.912 MHz LVCMOS oscillators in 4-SMD packages from Mercury or competitors. Verify pinout compatibility and electrical parameters such as load capacitance and drive level. Ensure the replacement supports the same 1.8V supply and enable/disable control scheme to maintain circuit functionality.
