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 voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs. Validate that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or tape-and-reel configurations.
