Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any recent revisions to the 18QHTF21 series that may affect mechanical dimensions or performance characteristics before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The 4-SMD package offers a small footprint compared to larger oscillator packages. Ensure the application does not require differential outputs, as this model provides single-ended LVCMOS signals. Verify thermal requirements against the specified operating temperature range.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a consistent small form factor. Mercury Electronics specializes in quartz-based timing components, providing reliable solutions for consumer electronics and industrial applications requiring stable clock signals.

Oscillators Replacement Considerations

Direct replacements must match the 40.572 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference with other manufacturers' 4-pin SMD oscillators ensuring identical pin definitions and electrical parameters to guarantee functional compatibility without circuit redesign.
