你好，
我们在对自行设计的3104板卡进行信号测试时，发现DOUT线上有异常电平，上下方向均有，如附图一与附图二所示；此外，在WCLK线上可以发现明显地串扰，如附图三所示，串扰频率与BCLK一致，layout上检查除了器件出口处外，板上走线WCLK与BCLK有足够间距。
以上现象在TI的评估套件TLV320AIC314EVM-K中也有，所以我们认为这是片子本身带出的信号。
我想了解这是否是正常现象或者是已知的故障？对使用有无具体影响？
我们片子配置在主模式，DSP mode, MCLK 12MHz由外部提供，BCLK 256KHz与WCLK 8KHz从MCLK分频生成。
谢谢！

你好，能否帮我转给对方：
So far we haven't got the wrong tune recording even in the high-temperature or low-temperature environment, the function till now seems good.
The waveforms are shown in the following: where the green is BCLK, the blue is WCLK, and the yellow is DOUT.
Glitches on the high side are frequent, they usually accompany WCLK but sometimes just align BCLK without WCLK. The low-side glitches are less frequent. We didn't capture glitches without WCLK on the low side, but maybe it's due to insufficient samples.
Our main concern is the glitches, they look strong and very close to the sample edge.
Please advise. Thank you.
