Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply voltage aligns with the system power rails. Confirm that the enable/disable pin configuration matches the control logic levels used in the application to prevent unintended oscillator states during operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The 4-SMD no-lead package offers a small footprint suitable for dense PCB layouts. Consider the enable/disable feature if dynamic power saving is necessary for the specific application scenario compared to always-on oscillators.

Oscillators Part Context

This part belongs to the standard XO series from Mercury Electronics, which specializes in quartz frequency control products. The manufacturer has decades of experience in Taiwan's quartz industry. This specific model represents a standard frequency option within their SMD oscillator lineup, targeting general-purpose timing needs.

Oscillators Replacement Considerations

Direct substitutes must match the 30.22 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pin compatibility and enable/disable logic polarity. Cross-reference with other manufacturers offering similar low-profile oscillators with identical electrical specifications.
