Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm availability and exact specifications. Ensure the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD package dimensions with PCB layout constraints to ensure mechanical fit.

Oscillators Selection Notes

Select this component when a 29.9 MHz reference is required with low voltage operation. The LVCMOS output is appropriate for standard digital logic families. Consider the enable/disable functionality if power efficiency during idle states is a design priority. Verify temperature range requirements against the datasheet specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series provides standardized XO solutions for mass production environments. The manufacturer has established history in quartz crystal production, offering consistent quality for frequency control applications.

Oscillators Replacement Considerations

Direct substitutes must match the 29.9 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check equivalent models from other manufacturers for pin-compatible alternatives if Mercury stock is unavailable.
