Procurement Notes
Verify the specific suffix OE against official Mercury Electronics documentation to confirm enable/disable functionality and exact electrical parameters. Ensure the 1.8V supply requirement aligns with target system design. Confirm package dimensions match PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a 67.515 MHz frequency is required with LVCMOS outputs. Consider the 1.8V operating voltage and enable/disable pin availability. Evaluate the 4-SMD no-lead package size against available board real estate. Compare against other Mercury series oscillators if different frequencies or voltage levels are needed.
Part Context
This part belongs to the Mercury Electronics XO (Crystal Oscillator) family. It shares the 18QHTF21 series designation with similar models like the 18QHTF21-75.630-OE. The series typically offers standard performance characteristics with various frequency options and control features.
Replacement Considerations
Direct substitutes may include other 67.515 MHz LVCMOS oscillators from Mercury Electronics with compatible packages. Verify equivalent electrical specifications and pinout compatibility before substitution.
