Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 3.3V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge sensitivity during assembly.

Selection Notes

Select this component when a 10.1405 MHz frequency is required with LVCMOS outputs. Consider the 3.3V operating voltage and the need for power-down capabilities. Evaluate the 2.0x1.6mm package size against available board space. Compare performance metrics such as phase noise and stability if available in official documentation to ensure suitability for the specific application environment.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options in a small form factor. Similar models include variants with different frequencies like 50 MHz or 51.2 MHz, and other voltages such as 1.8V. The 'PD' suffix typically indicates the inclusion of a power-down feature.

Replacement Considerations

Direct substitutes may include other 10.1405 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6mm package from Mercury Electronics or other manufacturers. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with similar part numbers in the same series for potential drop-in replacements.
