Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific environmental operating temperature ranges required by your application to ensure reliability under all conditions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS outputs. The enable/disable functionality makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor of the 4-SMD package for space-constrained layouts. Verify that the 14.74566 MHz frequency meets the baud rate or clock division needs of the target peripheral.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard clock oscillators. The model number indicates the specific frequency variant within the 18QHTF21 family. Mercury Electronics specializes in quartz crystals and frequency control products, offering various oscillator types including TCXOs and VCXOs for different precision requirements.

Oscillators Replacement Considerations

Direct substitutes must match the 14.74566 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference with other manufacturers' 1.8V LVCMOS oscillators in similar footprints. Ensure electrical parameters such as current consumption and start-up time are compatible with the original design requirements.
