C Bus
4 RX1 I Receiver Channel 1 Pin
5 RX2 I Receiver Channel 2 Pin
6 RX3 I Receiver Channel 3 Pin
7 INT O Interrupt Pin
VOUT O V-bit Output Pin for Receiver Input
DZF O
Zero Input Detect Pin
When the input data of DAC follow total 8192 LRCK cycles with “0” input data, this
pin goes to “H”. And when RSTN1 bit is “0”, PWDA bit is “0”, this pin goes to “H”.
8
OVF O
Analog Input Overflow Detect Pin
This pin goes to “H” if the analog input of Lch or Rch overflows.
9 CDTO O Control Data Output Pin in Serial Mode and I2C pin = “L”.
10 LRCKB I/O Channel Clock B Pin
11 BICKB I/O Audio Serial Data Clock B Pin
12 SDTOB O Audio Serial Data Output B Pin
13 OLRCKA I/O Output Channel Clock A Pin
14 ILRCKA I/O Input Channel Clock A Pin

19 DVSS - Digital Ground Pin, 0V
20
DVDD -
Digital Power Supply Pin, 4.5V∼5.5V
21 XTI I X'tal Input Pin
22 XTO O X'tal Output Pin
23 TX O
Transmit Channel Output pin
When DIT bit = “0”, RX0~3 Through.
When DIT bit = “1”, Internal DIT Output.
24 MCLK2 I Master Clock Input Pin
25 PDN I
Power-Down Mode & Reset Pin
When “L”, the AK4683 is powered-down, all registers are reset. And then all digital
output pins go “L”. The AK4683 must be reset once upon power-up.
CDTI I Control Data Input Pin in Serial Mode and I2C pin = “L”.
26
SDA I/O Control Data Pin in Serial Mode and I2C pin = “H”.
