AD2428 传输音频信号时,上下行的最大通道数分别是多少?

Thread Summary

The user encountered issues configuring 32-channel upstream and downstream audio transmission for AD2428 in Sigma Studio 4.7, despite the data sheet stating support for up to 32 channels. The final answer suggests that Table 3-5 in the technical reference manual provides the maximum limits, and the issue might be due to a bug affecting the automatic slot calculation. The solution involves manually selecting the correct slots in the Device Properties of the sub-nodes and re-downloading the configuration via USBi.

芯片手册 www.analog.com/.../ad2426-ad2427-ad2428.pdf 中有描述说上下行分别支持最多32通道的音频传输:



 
在参考手册 www.analog.com/.../ad242x-trm.pdf 的 Table3-5: Bandwidth Examples 表中记录的最大数分别是 51 和 34。

但是我按照这个表在 Sigma Studio 4.7 中配置时,提示 



甚至,我只是配置下行发送 28通道,24bit 的数据,也会提示错误:




所以,我不清楚 AD2428 的上下行最大通道数是多少,还是说我忽略了其他配置?
