Oscillators Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with system design constraints. Confirm the 4-SMD package footprint matches the PCB layout to avoid assembly issues.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6 mm form factor makes it suitable for space-constrained designs. Consider the standby feature if power efficiency during idle states is a priority for the application.
Oscillators Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a consistent small outline package format. Mercury Electronic is a recognized manufacturer of quartz crystals and frequency control products based in Taiwan.
Oscillators Replacement Considerations
Direct substitutes may include other 18.414 MHz LVCMOS oscillators in 4-SMD packages from different manufacturers, provided pinouts and electrical specifications match. Verify that alternative parts support the same 1.8V supply and standby functionality.
