Oscillators Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct voltage and frequency specifications. Confirm that the OE variant matches the required enable/disable pin configuration. Cross-reference the package outline drawing to verify compatibility with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Oscillators Selection Notes

Select this component when a precise 14.218 MHz clock source is required for 1.8V logic systems. The small 2.0x1.6 mm footprint makes it suitable for space-constrained designs. Consider the enable/disable feature if power management during idle states is necessary. Verify that the LVCMOS output swing is compatible with the input thresholds of the receiving digital components.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature crystal oscillators. The series typically offers various frequencies and supply voltages within a standardized small outline package.
