Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper mechanical fit and solder joint integrity during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 54.78125 MHz clock source. The LVCMOS output is suitable for standard digital logic families. Consider the small form factor for space-constrained designs. Verify that the enable pin can be effectively managed by the host controller to meet power management goals.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series offers various frequencies and voltages. The 'OE' suffix typically denotes the enable feature. This model represents a specific frequency variant within the standard XO category, providing a stable clock reference for electronic circuits requiring precise timing synchronization.

Oscillators Replacement Considerations

Direct substitutes must match the 54.78125 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check datasheets for compatible parts from other manufacturers offering identical electrical parameters and pin configurations to ensure seamless integration without redesign.
