Oscillators Procurement Notes

Verify the specific model suffix against official manufacturer documentation to ensure compatibility with required voltage levels and pin configurations. Confirm that the 1.8V supply requirement aligns with the target system design. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the operating temperature range meets the environmental conditions of the intended application environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. Consider the ±50ppm frequency stability sufficient for general timing applications rather than high-precision references. Evaluate the 4-SMD footprint constraints against available PCB real estate. Compare the enable/disable feature requirements against other fixed-output oscillators in the series.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, characterized by low-voltage operation and small form factors. The series includes various frequencies such as 21.333333 MHz and 57.750333 MHz, all sharing similar package and electrical characteristics. The 'OE' suffix typically denotes the enable/disable capability within this product line.

Oscillators Replacement Considerations

Direct substitutes include other models within the same 18QHTF21 series offering identical voltage and package specifications. Cross-reference part numbers like 18QHTF21-21.333333-OE for functional similarity if frequency differences are acceptable. Verify pinout compatibility before replacing with generic LVCMOS oscillators.
