Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable and within the specified operating range. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to ensure proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a 16.893 MHz clock source is required with low power consumption constraints. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. Consider the small 2.0x1.6 mm package size if space is limited on the PCB layout. Verify compatibility with LVCMOS input stages of the receiving logic gates.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies in a standardized 4-SMD package. The 'PD' suffix typically indicates the inclusion of a power-down feature, allowing the oscillator to be disabled to save energy when not in use, which is critical for battery-operated applications.

Oscillators Replacement Considerations

Direct replacements must match the 16.893 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check manufacturer-specific pinouts and electrical characteristics for compatibility.
