【急】关于PCM1808芯片DATA端口始终为0的问题,还请及时答复,谢谢!

Other Parts Discussed in Thread: PCM1808

PCM1808工作在256fs   master模式下,配置mclk使其工作在32kHz的采样率上,初次小批量打板,发现存在1/3的不良,故障原因为I2S口的DAT端口在上电时会吐出数据,一段时间后直接拉低到0V,极其像SPEC中描述的fade out功能,但此时的ADC的analog input端口始终在灌输数据,不应当进入fade out功能才对,此时的BCk和LRCLK工作的频率都是正常的,唯独DAT端口始终为0,还请大神及时回复,急啊,面临再次打板的计划,谢谢!
