Crystals Procurement Notes

Verify the specific suffix 'E' against official CTS documentation to confirm pin configuration and marking details, as variations exist within the 405 series. Ensure the design-in process accounts for the specified 18 pF load capacitance requirements of the host circuit. Confirm that the 60 Ohm ESR limit aligns with the oscillator circuit drive level specifications to prevent over-driving the crystal.

Crystals Selection Notes

Select this component when a 16.384 MHz fundamental frequency is required with ±30 ppm initial tolerance. The 4-SMD footprint suits automated assembly processes. Consider the 60 Ohm ESR value for oscillator circuit design. Verify compatibility with the target application's temperature range requirements, as this model supports extended industrial conditions compared to commercial grade alternatives.
