TI中文支持网OMAPL138如果采用25MHz晶振作为外部时钟输入的话，对晶振的频率稳定度指标有什么要求？
Shine：
在数据手册上有说明。For input clockfrequencies between 20 and 30 MHz, a crystal with 60 ohm max ESR is recommended. Typical load capacitance values are 10-20 pF, where the load capacitance is the series combination of C1 and C2.6.5 Crystal Oscillator or External Clock Inputhttp://www.ti.com/lit/ds/symlink/omap-l138.pdf
