Procurement Notes
Verify the specific supply voltage requirement of 1.8V against your circuit design to ensure compatibility. Confirm that the LVCMOS output levels match your receiving logic inputs. Check the SMD2016-4P footprint dimensions on your PCB layout to guarantee proper physical fitment during assembly.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a precise 6.312 MHz reference frequency. The enable/disable feature makes it suitable for battery-powered applications where power conservation is critical. Ensure the application environment supports standard XO performance without requiring temperature compensation.
Part Context
This part belongs to the Mercury Electronic 18QHTF series of surface-mount crystal oscillators. The manufacturer, established in Taiwan, specializes in quartz-based frequency control products including crystals, filters, and oscillators. This series provides standardized timing solutions for various electronic industries.
Replacement Considerations
Direct substitutes include other 6.312 MHz LVCMOS oscillators from Mercury Electronics with identical 1.8V supply and SMD2016-4P packaging. Verify pinout compatibility and electrical specifications before swapping with components from different manufacturers.
