Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 20.6 MHz reference is needed with low voltage operation. Consider the enable pin feature if dynamic power saving is required. Evaluate the small form factor for space-constrained designs. Compare performance against other LVCMOS oscillators in the same series for compatibility.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical package. The series provides standardized LVCMOS outputs for digital interfaces. Other variants in the line include different frequencies such as 44.2 MHz or 50.256 MHz while maintaining identical electrical and mechanical specifications.

Oscillators Replacement Considerations

Direct substitutes may include other 20.6 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package. Verify pinout compatibility and voltage levels before substitution. Cross-reference with similar Mercury Electronics parts like the 18QHTF21-25.1658-OE for mechanical fit, though frequency differs.
