Procurement Notes

Verify the specific orderable part number against the manufacturer's current catalog to ensure compatibility with your design requirements. Confirm that the 1.8V supply voltage aligns with your system's power rails. Check for any updated environmental compliance certifications such as RoHS status directly from the supplier documentation before finalizing procurement decisions.

Selection Notes

Select this component when a 14.08 MHz reference frequency is required for digital logic interfaces. Ensure the host circuit can provide a stable 1.8V supply rail. Consider the 4-SMD package size constraints during PCB layout planning. Verify that the LVCMOS output swing matches the input threshold requirements of the receiving logic gates or microcontrollers in the target application.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage surface-mount timing solutions. The series typically offers various frequency options within a standardized footprint.
