Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational needs. Confirm that the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to ensure compatibility with your target application environment.

Selection Notes

Select this component when a 13.225625 MHz clock source is required with low voltage operation. Consider the LVCMOS output compatibility with downstream digital logic. Evaluate the enable/disable feature if power efficiency during idle states is critical. Compare package dimensions against available board space. Verify temperature range suitability for the intended operating environment.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'OE' suffix typically denotes specific ordering or packaging variations defined by the manufacturer. This family provides reliable frequency control solutions for consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with different frequencies such as 18QHTF21-18.5625-OE or 18QHTF21-13.1313-OE if frequency adjustment is permissible. Ensure any replacement maintains the same 1.8V supply, LVCMOS output, and 4-SMD package form factor to fit existing designs without modification.
