Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The small 2.0x1.6 mm form factor makes it suitable for space-constrained designs. Consider the enable pin feature if dynamic power saving during idle states is necessary for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which focuses on miniature surface-mount oscillators. The series typically offers various frequency options within a standardized small outline package. Mercury Electronics leverages its history in quartz crystal manufacturing to provide stable frequency control solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 15.5 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and enable/disable logic polarity. Cross-reference with other manufacturers offering similar ultra-small footprint oscillators with identical electrical characteristics.
