Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your board's power rails. Ensure the 4-SMD package footprint matches your PCB layout. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.

Oscillators Selection Notes

Select this component when a 14.950 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage as a primary constraint for power supply design. Evaluate the need for standby functionality if power efficiency is critical. Compare the physical dimensions of the 4-SMD package against available board space. Verify that the manufacturer's specifications meet your jitter and stability requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage levels. The 'PD' suffix indicates the presence of a power-down feature. Mercury Electronic is a established manufacturer of quartz crystals and frequency control products, providing these components for industrial and consumer electronics markets.

Oscillators Replacement Considerations

Direct substitutes must match the 14.950 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers offering similar XO specifications to ensure functional equivalence without redesigning the PCB footprint.
