Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly and long-term performance stability.

Oscillators Selection Notes

Choose this model when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The compact 2.0x1.6 mm package makes it suitable for applications where board space is limited. Consider the standby feature if power management is critical for battery-operated devices. Ensure the operating temperature range meets your environmental specifications, as variations may exist within the product line.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile timing solutions. The series typically offers various frequencies and voltage options. Mercury Electronics specializes in quartz crystals and oscillators, providing components for consumer electronics and industrial applications. The 'PD' suffix likely indicates the power-down capability included in this specific variant.

Oscillators Replacement Considerations

Direct substitutes must match the 22.85715 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and thermal characteristics. Other models in the 18QHTF21 series with different frequencies may share the same package but require frequency validation. Cross-reference with other manufacturers offering similar low-profile XO specifications.
