Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 3.3V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check the enable pin polarity to ensure correct integration with your control signals. Review the datasheet for operating temperature range compliance.

Selection Notes

Select this component when a precise 13.5468 MHz reference is required for digital circuits. Consider the 3.3V operating voltage and LVCMOS output characteristics for compatibility. The small 2.5x2.0mm footprint makes it suitable for dense PCB layouts. Evaluate the enable/disable feature if power conservation during idle states is necessary. Compare performance metrics such as phase noise and stability against alternative oscillators.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series offers various frequencies and voltage options. Similar models include variants with different frequencies like 13.513 MHz or 35.4686 MHz. The series supports both 1.8V and 3.3V operations. Package types vary between 2.0x1.6mm and 2.5x2.0mm sizes depending on the specific model configuration.

Replacement Considerations

Direct substitutes may include other 13.5468 MHz LVCMOS oscillators with identical 3.3V operation and 2.5x2.0mm packaging. Verify pinout compatibility and electrical specifications before substitution. Models like 18QHTF21-13.513-OE share similar form factors but differ in frequency. Ensure the replacement maintains the same enable/disable logic and output drive strength.
