I am working with CC430F6137. I have successfully selected a 26Mhz crystal (2 pins,DIP ) to complete the wireless communication.
This time I want to minimize the size of the PCB board and select a crystal with the same capability(±20ppm) (4pins, SMD). However, the communication is not successful now. The circuit board is exactly same with that before. 2 diagnal pins of the crystal are connected to GND, and the other two are connected with RF_XINT and RF_XOUT.
Should I change the capacitance(C21 , C22) or it there anthing wrong?
Can anyone help me ?
Thank you!
