Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the 4-SMD no lead package footprint matches your PCB layout constraints. Check for any specific environmental qualification data if operating in extreme temperatures. Validate that the LVCMOS output swing is compatible with the input thresholds of the receiving logic circuitry.

Oscillators Selection Notes

Select this oscillator when a stable 14.592 MHz reference is required with minimal power consumption. The 1.8V operation makes it suitable for modern low-voltage digital designs. Consider the standby feature for applications requiring periodic sleep modes. The small form factor aids in dense PCB layouts. Ensure the application does not require spread-spectrum capabilities, as this is a standard XO model.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same package and electrical specification framework. The series includes models like 18QHTF21-51.200-PD and 18QHTF21-50.2067-PD, sharing similar physical dimensions and voltage characteristics but differing in output frequency. This standardizes design reuse across different product lines requiring varied clock speeds.

Oscillators Replacement Considerations

Direct replacements must match the 14.592 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers' equivalent SMD oscillators offering identical electrical parameters and mechanical footprint to ensure seamless integration without redesigning the PCB.
