LC890561W
• DTMA[4:0], DTMB[3:0] and DTMC[2:0] commands have the same address. Therefore, they can be set up together.
• Each command setting value is assigned to output data according to the sampling frequency of input data.
• Delay time is set up with the number of frames which is obtained by multiplying the sampling frequency calculation
value of input data by the setting value of DTMA[4:0], DTMB[3:0] and DTMC[2:0] commands.
• Delay time can be freely switched within the range where the setup is possible.
• This setup is continued until it is canceled (delayed 0ms, non delay).
• This function is not performed when mode 4, “Input fs free mode B”, by MODE0 and MODE1 is set. Even the above
setting is set, it will be invalid.
13.1.2 Output Data Delay Setup of SDIN Input Data (DTMX[4:0], DTMY[3:0])
• Output data delay of SDIN input data is set up by DTMX[4:0] and DTMY[3:0] commands.
• SDIN input data needs to synchronize with BCK and LRCK output clocks. Therefore, the sampling frequency of
SDIN data is decided by setup of XSEL (XIN input clock frequency). In other word, input data is either 48kHz or
96kHz, and uses a setup of either DTMX[4:0] or DTMY[3:0] commands.
• Delay time can be freely switched within the range where the setup is possible.
• This setup is continued until it is canceled (delayed 0ms, non delay).
• The following delay time is performed when mode 4, “Input fs free mode B”, by MODE0 and MODE1 is set.
Delay time = {(256fs × delay time of DTMX [4:0] or DTMY [3:0]) / XIN input clock}
