Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm pinout and electrical characteristics. Ensure the operating temperature range meets system requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 1.8V supply voltage aligns with the target circuit design before procurement.

Selection Notes

Select this component when a precise 72.4005 MHz reference is required in a low-voltage environment. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V supply constraint and the need for an enable pin when designing the power sequence. The small footprint makes it suitable for high-density PCB layouts where space is limited.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal products. The series offers various frequencies and packages.
