Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range requirements against the official datasheet before procurement. Ensure that the 1.8V supply voltage aligns with the target circuit design. Confirm the 4-SMD package footprint matches the PCB layout constraints. Check for any specific handling instructions regarding the no-lead package during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm form factor makes it appropriate for dense board layouts. Consider the availability of the standby feature if power management is a priority. Validate that the 33.02584 MHz frequency meets the system's timing specifications without additional dividers.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The manufacturer has a history dating back to 1973, focusing on frequency control products. This series typically offers standard XO options with various frequencies and supply voltages, catering to diverse electronic timing needs.

Oscillators Replacement Considerations

Direct substitutes may include other 18QHTF21 variants with different frequencies but identical pinouts and electrical characteristics, such as 18QHTF21-33.333-PD, provided the frequency difference is acceptable. Cross-referencing with other manufacturers' 33.02584 MHz LVCMOS oscillators in 4-SMD packages requires careful verification of voltage and pin configuration.
