Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The enable/disable pin allows for power management optimization in battery-operated devices. Consider the small form factor suitable for dense board layouts where space constraints limit larger oscillator packages.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD Oscillator series, specifically the H21 or similar compact lineages. It represents a standard XO (Crystal Oscillator) variant within their portfolio of frequency control products. The manufacturer has decades of experience in quartz crystal production, positioning this component as a reliable timing solution for consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 32.25 MHz LVCMOS oscillators from Mercury such as the 18QHTF21-32.256-OE if frequency variance is acceptable. Cross-reference with other manufacturers offering identical 1.8V, 4-SMD LVCMOS profiles ensuring pinout compatibility.
