Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable pin logic levels are compatible with your controlling microcontroller or FPGA outputs to prevent unintended state changes during operation.

Oscillators Selection Notes

Select this component when a 16.0028 MHz clock signal is required in a 2.0x1.6mm footprint. It is appropriate for designs prioritizing low power consumption due to the 1.8V operating voltage. Consider the enable feature if dynamic power saving is necessary. Compare against other Mercury 18QHTF series variants for different frequencies or voltage levels if specifications do not match exactly.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized small outline package. These components are commonly used as primary clock sources in portable devices and industrial controllers where size and power efficiency are critical constraints.

Oscillators Replacement Considerations

Direct replacements must match the 16.0028 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as rise/fall times and duty cycle. Cross-reference with other manufacturers offering equivalent SMD oscillators only if mechanical and electrical specs are identical.
