• Includes standby mode for power management
• Utilizes a compact surface-mount package

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm the 4-SMD package dimensions fit the PCB layout constraints. Cross-reference the part number suffix to ensure the correct variant is ordered.

Oscillators Selection Notes

Select this component when a precise 13.846154 MHz clock source is required with low voltage operation. Consider the LVCMOS interface compatibility with downstream logic. Evaluate the need for standby functionality to meet power efficiency goals. Verify that the 1.8V operating range matches the available power rails in the application circuit.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small form factor. The series typically targets applications requiring stable clock signals in space-constrained environments. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 13.846154 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check Mercury Electronics documentation for alternative part numbers with identical electrical characteristics. Verify pinout compatibility if replacing with components from other manufacturers.
