AD1974往上調(diào)整MCLK/XI的頻率到一定程度時(shí),MCLKO/XO就會(huì)量測到Jitter非常大的訊號是為什么?

ADC 控制控制2:0x48 但從MCLKO/XO卻量測到153kHz輸出,并且I2S訊號也未輸出,SPI已確定能夠正常讀寫。 我試著往上調(diào)整MCLK/XI的頻率到一定程度時(shí),MCLKO/XO就會(huì)量測到Jitter非常大的訊號。 請問是否在電路上有什么地方需要注意? 或是寄存器設(shè)定要如何修改? 謝謝您。

簡單理解抖動(dòng)Jitter測量

抖動(dòng)jitter的有關(guān)概念和理論很多,容易把人抖暈;本文目的是幫助產(chǎn)品研發(fā)和測試工程師,不需要研究時(shí)頻域抖動(dòng)測量的原理和公式,只講用什么手段測抖動(dòng),以及測試值的表達(dá)含義。
