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 constraints. Cross-reference the enable pin functionality with the microcontroller or logic gate outputs to ensure proper control integration during the assembly phase.

Oscillators Selection Notes

Select this component when a 30.4 MHz reference is required for LVCMOS compatible circuits. The 1.8V operating voltage makes it suitable for low-power portable devices. The enable/disable feature allows for dynamic power management strategies. Consider the thermal performance and stability requirements of the application environment to ensure long-term reliability within the specified operating temperature range.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The manufacturer has extensive experience in quartz crystal production. This specific model represents a surface-mount solution designed for modern electronic assemblies requiring reliable clock signals in compact form factors.

Oscillators Replacement Considerations

Direct substitutes include other 30.4 MHz LVCMOS oscillators in 4-SMD packages from Mercury Electronics, such as the 18QHTF21-30.400 variant without the OE suffix if enable functionality is not critical. Verify pinout compatibility and electrical specifications before substitution.
