■ Double Sampling Frequency Mode
When MONO bit = “1”, the AK4118A outputs data in double speed according to “Single channel double sampling
frequency mode” of AES3. For example, when 192kHz mono data is transmitted or received, L/R channels of 96kHz
biphase data are used. In this case, one frame is 96kHz and LRCK frequency is 192kHz.
