Description

Ip

Reset pin

–

0 V ground pin

Ip

B C KO and LRCO mode set. Outputs (master mode) when LOW , and inputs (slave mode) when

HIGH.

Ip

DOUT through mode set. Normal mode when HIGH, and through mode when LOW.

Ip

Output system clock (OCLK) select. 384fso when HIGH, and 256fso when LOW .

I

Output system clock input

I/O Output word clock input/output (fso). Input/output mode set by the level on SLAVE.

I/O Output bit clock input/output. Input/output mode set by the level on SLAVE.

O

Data output

1. Pins which have the same name are connected internally. Accordingly, circuit connections can be made to either pin or to both pins.

2. I = input, Ip = Input with pull-up resistor (HIGH-level pins can be left open), O = output, I/O = input/output

3. fsi is the input word clock (LRCI) frequency, and fso is the output word clock (LRCO) frequency.
