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 rail is stable and within operational limits. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this component when a precise 14.7457 MHz clock source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-voltage 1.8V operating profile and the inclusion of an enable pin for power management. Consider the physical constraints of the 4-SMD No Lead package for space-limited designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, which offers various frequencies within the same package and electrical specification framework. The suffix -OE typically denotes a specific ordering or packaging variant within the manufacturer's catalog, while the core model defines the electrical characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 14.7457 MHz frequency, LVCMOS output type, and 1.8V supply voltage. Compatible alternatives include other models from the 18QHTF21 series with identical pinouts and electrical parameters, ensuring no functional changes due to ordering suffixes.
