Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and package configuration. Confirm that the OE variant matches the required enable/disable functionality. Check datasheet specifications for operating temperature range and load capacitance requirements before integration. Ensure compatibility with the target system's power supply and logic levels.

Selection Notes

Select this component when a 1.8V supply is available and LVCMOS outputs are required. Consider the small 2.0x1.6mm footprint for dense PCB layouts. Evaluate the need for enable/disable control versus always-on operation. Compare against other frequencies in the QHTF21 series if different timing is needed.

Part Context

This part belongs to the QHTF21 series of surface mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 18 prefix indicates the 1.8V supply variant. The -OE suffix typically denotes specific pinout or enable features within the manufacturer's lineup.

Replacement Considerations

Direct substitutes include other 75.913 MHz LVCMOS oscillators in 4-SMD packages. Verify voltage tolerance and enable logic polarity. Cross-reference with similar Mercury parts like 25QHTF21 variants if 2.5V is acceptable.
