Crystals Procurement Notes

Verify the specific suffix against the official TXC ordering guide to ensure correct packaging and tolerance specifications. Confirm that the 10pF load capacitance aligns with the target oscillator circuit design. Check current availability status as automotive components may experience supply fluctuations. Ensure compliance with RoHS directives for the intended market.

Crystals Selection Notes

Select this component when a 27MHz reference is required for automotive-grade environments. The 80 Ohm ESR must be compatible with the host MCU or transceiver oscillator input. Designers should account for the 10pF load capacitance in PCB layout calculations to maintain frequency accuracy within the specified ±30 ppm range across the operating temperature.
