Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the specified operating range. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper solder joint formation and mechanical reliability during assembly.

Oscillators Selection Notes

Select this component when a precise 45.75 MHz timing source is required with low voltage operation. Consider the enable/disable feature if power management is critical for the application. Evaluate the LVCMOS output swing against the input thresholds of the receiving logic gates. Compare package size constraints with available board space to ensure the 4-SMD form factor fits the design layout without interference.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of quartz crystal oscillators. The series offers various frequencies and supply voltages. The 'OE' suffix typically denotes the enable/disable pin configuration. Mercury Electronics specializes in frequency control products including crystals, TCXOs, and VCTCXOs, providing solutions for consumer electronics and industrial equipment requiring stable timing references.

Oscillators Replacement Considerations

Direct substitutes include other 45.75 MHz LVCMOS oscillators from different manufacturers with identical 1.8V supply and 4-SMD no-lead packages. Verify pinout compatibility, specifically the enable/disable pin assignment, as variations exist across brands. Check equivalent specifications for frequency stability and phase noise to ensure performance parity in the final application.
