Crystals Procurement Notes

Verify the authenticity of the component through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specified package dimensions and pin configuration. Check for any recent product change notices (PCNs) that may affect specifications. Ensure compliance with RoHS3 regulations if required for your specific application standards. Validate the date code to ensure freshness of the inventory.

Crystals Selection Notes

Select this component when a low-profile, surface-mount solution is required for 18.432 MHz timing. Consider its MEMS construction for improved shock resistance over traditional crystals. Evaluate the power consumption requirements against the 6mA maximum draw. Ensure the system voltage aligns with the 1.8V to 3.3V operational range. Verify that the ±50ppm stability meets the system's jitter tolerance needs.

Crystals Part Context

This part belongs to TXC Corporation's broader portfolio of MEMS oscillators, which are engineered to replace discrete crystals with integrated solutions. The TA series and similar lines demonstrate the manufacturer's focus on miniaturization and performance consistency. These components are typically used in applications where space constraints and long-term reliability are critical factors in design selection.

Crystals Replacement Considerations
