如何测试MAX9485具有晶体的功率等级

摘要：MAX9485就是一个多功能，可编程音频时钟发生器。它由一个VCXO，小数N分频PLL，I²C接口。使用MAX9485具有适当的，它是重要的VCXO晶体的功率水平不超过其最高评级。本应用笔记介绍了一种简单的方法测量晶体振荡器的功率水平，MAX9485具有测试结果报告。Maxim>AppNotes>AUDIOCIRCUITSCLOCKGENERATIONANDDISTRIBUTIONHIGH-SPEEDINTERCONNECTKeywords:Audioclockgenerator,MPEG2,AC-3,fractional-NPLL,VCXO,crystalpowerlevel,crystalmodel,Mar20,2006VCXOpowerlevel,I2CprogrammingAPPLICATIONNOTE3736HowtoTesttheCrystal'sPowerLevelintheMAX9485Abstract:MAX9485isaversatile,programmable,audioclockgenerator.ItconsistsofaVCXO,fractional-NPLL,andICinterface.TousetheMAX9485appropriately,itisimportantthatthepowerleveloftheVCXO'scrystaldoesnotexceeditsmaximumrating.Thisapplicationnotedescribesasimplemethodformeasuringthepowerlevelofacrystaloscillator,andreportsthetestresultsontheMAX9485.IntroductionTheMAX9485[1,2]isacost-effective,progr
