摘要： Teridian 单或 3 阶段能源计量 ICs，与外部 32786Hz 水晶，结合使用生成可能略有不同的频率。此应用程序说明解释的频率偏差的原因，并讨论了尽量减少这种影响的方法。 71M651x Energy Meter IC A Maxim Integrated Products Brand APPLICATION NOTE AN_651X_032 JANUARY 2011 Crystal Frequency Variations The frequency generated by the 71M6511 or 71M6513 in conjunction with the external 32786Hz crystal may vary slightly, depending on the way the IC is supplied with power. This Application Note explains the reason for the frequency deviation and methods that can be used to minimize this effect. AN_651X_032 REV1-2 Crystal Frequen……
