Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact pinout and electrical characteristics. Ensure the 1.8V supply requirement aligns with system design constraints before procurement. Cross-reference the 4-SMD No Lead package dimensions with PCB layout specifications to guarantee mechanical compatibility.
Selection Notes
Select this component when a 13.0625 MHz frequency is strictly required alongside LVCMOS compatibility. Consider the 1.8V operating voltage range to ensure compatibility with downstream logic levels. Evaluate the small 2.0x1.6 mm footprint against available board space. Confirm that the enable/disable feature meets power management requirements for the target application.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co. Ltd. The series offers various frequencies and voltage options within similar compact packages. The 'OE' suffix typically denotes specific operational or packaging variations defined by the manufacturer. This model represents a standard XO variant optimized for low-power digital applications.
Replacement Considerations
Direct substitutes include other 13.0625 MHz LVCMOS oscillators in 4-SMD No Lead packages with 1.8V operation. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult Mercury Electronics for alternative part numbers within the same series if availability is constrained.
