Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage and package specifications. Confirm that the manufacturer documentation aligns with the intended application requirements before procurement. Cross-reference the part number with official distributor catalogs to validate current availability and authenticity.

Oscillators Selection Notes

Select this component when a 1.8V supply is available and space constraints require a 2.0x1.6 mm footprint. Ensure the design accommodates the LVCMOS output swing and that the power-down pin can be effectively controlled by the host system to manage power consumption during idle states.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor frequency control solutions. The series typically offers various frequencies and voltage options within similar physical packages, allowing designers to maintain consistent board layouts across different product variants.

Oscillators Replacement Considerations

Direct substitutes include other 17.2 MHz LVCMOS oscillators in 2.0x1.6 mm packages from compatible manufacturers. Verify electrical parameters such as load capacitance and drive strength to ensure functional equivalence without circuit modification.
