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 target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 20.15 MHz reference is required for LVCMOS-compatible circuits. The integrated enable pin offers flexibility for power-sensitive designs. Consider the 1.8V operating voltage as a primary constraint. The small 2.0x1.6 mm package is suitable for space-constrained applications where standard through-hole or larger SMD oscillators cannot fit within the available board area.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz crystal products. The manufacturer has decades of experience in frequency control components. This specific model represents a standard XO variant optimized for modern low-power digital systems. The series typically offers various frequency options within a consistent physical footprint.

Oscillators Replacement Considerations

Direct substitutes include other 20.15 MHz LVCMOS oscillators in 4-SMD 2.0x1.6mm packages with 1.8V operation. Verify electrical parameters such as phase noise and jitter specifications match original requirements. Ensure compatible enable logic levels if active control is utilized in the design.
