I would like to know group delay specification of SSM2603.
On the datasheet, it seems no specification.
Roughly estimation value is OK. It is like that almost same as ADAU1979.
Thank you for your help as always.
I would use ADAU1361 Group Delay Data as it is more closer to the portable CODEC SSM2603. Please check Page 10 of ADAU1361 datasheet for Group delay numbers for ADC and DAC @48K sample rate.
Thank you very much for your response!
It's good reference!
