Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your environment.

Oscillators Selection Notes

Select this component when a precise 2.22 MHz clock source is required in space-constrained designs. The LVCMOS output ensures direct interfacing with standard digital logic without additional level shifting. Consider the low voltage requirement if your system operates on battery power or has strict power consumption limits. Verify that the package size fits within your assembly capabilities.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options.
