2 RCKI input Reference clock input.
3 NC unconnected No connection.
4 SDIN input Audio serial data input.
5 BCKI bidirectional Input port bit clock, I/O; the datasheet lists it as an input and output.
6 LRCKI bidirectional Input port left and right word clock, I/O; the datasheet lists it as an input and output.
7 VIO power_in Digital I/O supply, 1.65 V to VDD.
8 DGND power_in Digital ground.
9 BYPAS input ASRC bypass control input, active high.
10 IFMT0 input Input port data format control input.
11 IFMT1 input Input port data format control input.
12 IFMT2 input Input port data format control input.
13 RST input Reset input, active low.
14 MUTE input Output mute control input, active high.
15 RDY output ASRC ready status output, active low.
16 OWL1 input Output port data word length control input.
17 OWL0 input Output port data word length control input.
18 OFMT1 input Output port data format control input.
19 OFMT0 input Output port data format control input.
20 TDMI input TDM data input; connect to DGND when not in use.
21 DGND power_in Digital ground.
22 VDD power_in Digital core supply, 3.3 V (3.0 V to 3.6 V per recommended operating conditions).
23 SDOUT output Audio serial data output.
24 LRCKO bidirectional Output port left and right word clock, I/O; the datasheet lists it as an input and output.
25 BCKO bidirectional Output port bit clock, I/O; the datasheet lists it as an input and output.
