Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 22.7728 MHz reference is required for LVCMOS-compatible digital circuits. The choice is driven by the need for low-power operation at 1.8V and the convenience of integrated enable/disable controls. Consider the small form factor of the 4-SMD package if board space is limited. Validate that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation.
