terminals (SDO0-SDO3 terminal) are prepared for an output, the connection with external AD/DA
converter LSI is easy.
by 3-5 V, an output terminal (SDO0-3, LRCKOA, BCKOA, LRCKOB, and BCKOB terminal) is outputted by
3 V. Therefore, when the input terminal of external LSI does not correspond to TTL level input, please
carry out level conversion using a level shifter circuit etc.
signal has the same sampling frequency, it is restricted. Since a sampling frequency differs when the signal
of 2 fs is inputted and it outputs a signal by 1 fs, the connection method needs to be changed.
Since two terminals (SDI0 and SDI1 terminal) are prepared for an audio serial data input and four
Although an input terminal (SDI0, SDI1, LRCKA, BCKA, LRCKB, and BCKB terminal) can be inputted
Figure 22 the example of connection of AD/DA converter is shown. However, when an input-and-output
