CC2642R: Crystal and Balun recommendation

Ambroise Suter

Part Number: CC2642R

Hello,

We are working on a new design with the CC2642R, can we use the Balun/Crystal below?

Would you recommend to use other devices?

Thank you and best regards,

Ambroise

The crystal looks ok. The balun will not work well with CC2642R though, you need one that is designed for the CC26xx output impedance. Take a look at CC13xx/CC26xx Hardware Configuration and PCB Design Considerations (Rev. E) for details.
