Hi Xie-san,
Nice to see you and thank you for your response.
I confirmed again that they are using PCM mode with external digital filter. I apologize for the confusion.
Please let me state again their condition as below.
Our goal is to clarify that they achieve correct operation with SCK=128fs and following conditions. Actually they confirmed correct operation with SCK=128fs but it could not be operated with SCK=512fs, so they would like to know if 128fs is appropriate setting.
---[Customer's setting]---
- PCM mode
- with external digital filter
- DFMS = 0
- OS[1:0] = 00
- fs = 48kHz
- WDCK = 8fs
- BCK = 256fs
- SCK = 128fs
- Audio Data Word = 32bit
---[My Question]---
They can not see correct operation with SCK=512fs and above setting, but the table2 in datasheet shows SCK=512fs is acceptable with their setting.
Is the table2 applied for application of external digital filter?
Best Regards,
Sonoki
