Oscillators Procurement Notes
Verify the specific suffix 'OE' against official datasheets to confirm enable/disable functionality and voltage levels. Ensure the operating temperature range meets application requirements. Confirm package footprint compatibility during PCB layout. Cross-reference part numbers with manufacturer documentation to avoid substitution errors.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V clock source is required. Consider the enable/disable feature for power-sensitive designs. Evaluate the small 2.0x1.6mm footprint for space-constrained layouts. Verify LVCMOS compatibility with downstream logic circuits before integration.
Oscillators Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronics, designed for general-purpose timing applications. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific operational characteristics or packaging variants within the product line.
Oscillators Replacement Considerations
Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages with similar frequencies. Verify electrical parameters and pinout compatibility before replacement. Consult manufacturer cross-reference lists for approved alternatives.
