LC-37D90U
5 – 24
8 DZF O Zero Input Detect.
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”.
9 CDTO O Control Data Output in Serial Mode and I2C pin= “L”.
10 LRCKB I/O Channel Clock B.
11 BICKB I/O Audio Serial Data Clock B.
12 SDTOB O Audio Serial Data Output B.
13 OLRCKA I/O Output Channel Clock A.
14 ILRCKA I/O Input Channel Clock A.
15 BICKA I/O Audio Serial Data Clock A.

17 MCKO O Master Clock Output.
18 TVDD --- Output Buffer Power Supply, 2.7V~5.5V.
19 DVSS --- Digital Ground.
20 DVDD --- Digital Power Supply, 4.5V~5.5V.
21 XTI I X'tal Input.
22 XTO O X'tal Output.
23 TX O Transmit Channel Output.
When DIT bit= “0” , RX0~3 Through.
When DIT bit= “1” , Internal DIT Output.
24 MCLK2 I Master Clock Input
25 PDN I Power-Down Mode & Reset.
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.
