DS692PP1
determines what the output sample rate will be based on the MCLK selected for SDOUT1, as shown in the
hardware control pin descriptions shown above. For SDOUT2, the output sample rate is dictated by the in-
coming AES3 data, and the master mode clock ratio determines the frequency of RMCK relative to the in-
coming AES3 sample rate. Note: if TDM Mode is selected for SDOUT1, then SDOUT1 cannot be set to
“Master, Fso = MCLK/128”.
