Pin Function
No. Pin Name I/O
1 V1 I Validity bit input
Audio routing mode (in synchronous mode)
2 TRANS I
0: Normal mode 1: Audio routing (transparent) mode
Power down and reset
3 PDN I This unit becomes powered down state when turns this pin into "L", and TXP/N pin becomes "L" and a
register is initialized.
4 MCLK I Master clock input
5 SDTI I Audio serial data input
Audio serial data clock I/O
6 BICK I/O
Serial clock for SDTI pin This pin can change to output pin by setting of DIF2-0.
I/O channel clock
7 LRCK I/O
Shows the L/R channel This pin can change to output pin by setting of DIF2-0.
FS0 I Sampling frequency selection 0 (in synchronous mode)
CSN I Host interface chip select (in asynchronous mode)
8
AK4112B mode (in audio routing mode)
AKMODE I
0: Non-AKM receiver mode, 1: AK4112B mode
FS1 I Sampling frequency selection 1 (in synchronous mode)
9
CDTI I Host interface data input (in asynchronous mode)
FS2 I Sampling frequency selection 2 (in synchronous mode)
10
CCLK I Host interface bit clock input (in asynchronous mode)
FS3 I Sampling frequency selection 3 (in synchronous mode)
11
CDTO I Host interface data output (in asynchronous mode)
12 C1 I Channel status bit input
Asynchronous/Synchronous mode selection
13 ANS I
0: Asynchronous mode, 1: Synchronous mode
Block start I/O
14 BLS I/O In the normal mode, outputs "H" with first 4 bytes. It becomes input pin in the audio routing mode. When
PDN pin is "L" in the normal mode, BLS pin outputs "H".
15 CKS0 I Clock mode selection 0
16 CKS1 I Clock mode selection 1
