Other jumpers set up
[JP1](GND): Analog ground and digital ground
Open: Separated <default>
Short: Common (The connector “DGND” can be open.)
[JP2](DVDD): DVDD of AK4356
DVDD: Independent of AVDD <default>
AVDD: Same as AVDD (The connector “DVDD” can be open.)
[JP3](REG): AVDD of AK4356
Open: Supplied from “AVDD” connector
Short: Supplied from the regulator (The connector “AVDD” should be open.)
[JP10-12](SDTI1-3): SDTI of AK4356
DATA: Serial data <default>
GND:
“0” data
n
The function of the toggle SW
Upper-side is “H” and lower-side is “L”.
[SW1](-PD):
[SW2](SMUTE): Soft mute of AK4356. Bring “H” when using soft mute.
Resets the AK4356. Keep “H” during normal operation.
n
The indication content for LED
[D2] (VERF):
[D3] (PREM): Indicates whether the input data is pre-emphasized or not. LED turns on when the data is pre-
emphasized.
Monitors VERF pin of the CS8414. LED turns on when some error has occurred to CS8414.
n
Serial control mode
The AK4356 can be controlled via the printer port (parallel port) of IBM-AT
compatible PC. Connect PORT1(CR-I/F) with PC by 10-line flat cable
packed with the AKD4356.
Chip address can be selected by SW3(MODE1)-No.1(CAD1) and No.2(CAD0).
Take care of the direction of connector. There is a mark at 1pin.
The pin layout of PORT1 is as Figure 4.
Figure 4. PORT1 pin layout
n
Interface with AC3 decoder
PORT2(AC3) is used for interface with AC3 decoder.
MCLK, BICK, LRCK and 3-line serial data can be input
from the decoder via PORT2.
Pin layout of PORT2 is as Figure5.
In this case, JP4(LRCK), JP7(BICK), JP15(XTI), JP16(XTE),
JP14(DIR) and JP13(SDATA) should be set up as evaluation mode 4.
