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 power architecture. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your intended environment.

Oscillators Selection Notes

Select this model when a 14.04 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and the need for a power-down feature. The small 2.0x1.6mm package is ideal for space-constrained designs. Compare against other frequencies in the 18QHTF21 series if different timing is needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS output and 1.8V operation. The 'PD' suffix indicates the inclusion of a power-down pin or function. These components are designed for standard surface-mount assembly processes.

Oscillators Replacement Considerations

Direct substitutes within the same series include 18QHTF21-14.000-PD or 18QHTF21-14.318-PD if frequency adjustments are acceptable. Verify pinout and electrical characteristics match exactly. Cross-reference with other manufacturers offering 1.8V LVCMOS oscillators in 4-SMD packages.
