„ Other jumper pins set up
[JP1] (GND): Analog ground and digital ground
open: separated <default>
short: AGND and DGND are connected.
[JP2] (DZF) Mute circuit
ON: Used . Analog output are muted when DZF=”H”.
OFF: Not used. <default>
[JP6] (BICK_ PHASE): Phase of BCLK
THR: BICK is coincides with AK4380. <default>
INV: BICK is inverted.
„ The function of the toggle SW.
[SW1](PDN): Resets the AK4380. Keep “H” during normal operation.
[SW2](SMUTE): Soft mute of AK4380. Bring “H” when using soft mute.
[SW3](P/S):
H: parallel mode.
L: serial mode.
„ Indication for LED
[LED1] (VERF): Monitor VERF pin of the CS8414. LED turns on when some error has occurred to CS8414.
[LED2]: (PREM): Indicate whether the input data of CS8414 is pre-emphasized or not.
„ Serial control mode
PORT1
10 ^up-I/F 9
The AK4380 can be controlled via the printer port (parallel port) of IBM-AT
compatible PC. Connect PORT1(up-I/F) with PC by 10-line flat cable
packed with the AKD4380.
CSN
CCLK
Take care of the direction of connector. There is a mark at 1pin.
The pin layout of PORT1 is as Figure 2.
