Crystals Procurement Notes

Verify the specific load capacitance and frequency tolerance requirements against the system design specifications before procurement. Confirm that the operating temperature range meets the environmental conditions of the final application. Ensure compatibility with the PCB footprint and soldering processes required for 4-SMD packages. Cross-reference the manufacturer datasheet for detailed electrical characteristics and handling instructions.

Crystals Selection Notes

Select this component when a 38.4 MHz reference signal is required with moderate stability. Consider the 10 pF load capacitance requirement for circuit matching. Evaluate the ±20 ppm tolerance against the system's jitter and phase noise constraints. Compare the physical dimensions and thermal performance against alternative oscillators or crystals if tighter specifications are needed.
