NCK2910 operates in RX ON mode, and when the ambient temperature ranges from 15 ℃ to 60 ℃, 2910 stops working and an RF Event occurs, type 0xF4-PLL Unlock. Currently, we have checked the external crystal oscillator and found that the PPM value is within the range. May I ask if there are any other possible situations that may cause PLL Unlock during temperature difference changes？
