TI中文支持网cc2640r2f 外部24M晶振用示波示打显示23.8M和24.4M这样算在正常范围内嘛
Viki Shi：
请按照官方文档的要求选择晶振，此文档还列出了推荐的晶振型号：www.ti.com/…/swra495g.pdf

我这个晶振偏差算大还是小啊，能否给个量化的数据呢
Viki Shi：
回复 huijun li:
Because the 24-MHz crystal oscillator is used as a reference to generate the RF signal, any crystal frequency deviation is directly transferred to deviation of the RF signal. For example, 10 ppm leads a deviation in RF carrier frequency of 10 ppm. Select a crystal with performance within the limits of the RF specifications.
• For 802.15.4 (Thread/ZigBee®), the maximum deviation in carrier frequency is limited to ±40 ppm (see [1]).
• For Bluetooth Low Energy, the limit is ±40 ppm (see [2]).
