11. Serial Data Input-and-Output Terminal
Since two terminals (SDI0 and SDI1 terminal) are prepared for an audio serial data input and four
terminals (SDO0-SDO3 terminal) are prepared for an output, the connection with external AD/DA
converter LSI is easy.
Although an input terminal (SDI0, SDI1, LRCKA, BCKA, LRCKB, and BCKB terminal) can be inputted
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.
Figure 22 the example of connection of AD/DA converter is shown. However, when an input-and-output
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.
