„ Evaluation mode
The setup sequence from the initial state
The AKD4141 can evaluate various mode using AK4682 (CODEC), AK4114 (DIR) and AK4114 (DIT).
Set jumper pins and SW to condition to evaluate. About AK4141 and AK4682, refer to each
datasheet. About DIR and DIT, refer to Table 5.~ Table 10. in this manual.
Follows are setting examples of AK4141’s decoder.
Measurement path :
٠SIF (J1) → AK4141 (Stereo decoder) → DAC (AK4682) → LOUT1/ROUT1
٠SIF (J1) → AK4141 (Stereo decoder) → DIT (AK4141) → TX (PORT1)
Setting of AK4141 :
Using X’tal Oscillator, Master mode MCLK=256fjs, fs=48kHz.
(1) Setting of MCLK. X’tal Oscillator (X1) is used.
12.288MHz (fs=48kHz, MCLK=256fs) is equipped on the board by initial setting.
When evaluate it in other conditions, please attach a X’tal oscillator according to evaluation mode.
(2) Setting of DIP SW1.
(2-1) Setting of Master Mode
Please set MSN (No.6) of DIP SW1 to “H”. (Master Mode : MCKI=256fs)
(2-2) Setting of SIF input. Please set 6M5 pin and 4M5[2-0] pin according to carrier frequency.
(2-2-1) In case of including the 6.5MHz carrier.
6M5 (No.5) of DIP SW1 = “L” : L NICAM.
6M5 (No.5) of DIP SW1 = “H” : D/K
(2-2-2) In case of including the 4.5MHz carrier.
4M5[2-0] (No.4-2) of DIP SW1 = “LHL” : EIAJ.
4M5[2-0] (No.4-2) of DIP SW1 = “LLH” : M-Korea.
4M5[2-0] (No.4-2) of DIP SW1 = “LLL” : PAL (Chroma Carrier)
4M5[2-0] (No.4-2) of DIP SW1 = “HLL” : FM-Stereo Radio EU
4M5[2-0] (No.4-2) of DIP SW1 = “HHH” : FM-Stereo Radio US
(Note.) The details please refer to Table 4. in this manual.
(3) Setting of the jumper pins. Jumper pins should be set as follows.
Please set JP14 and JP16 according to the output of AK4141.
The following are setting examples of JP14=SDTO1 and JP16=SDTO2.

(4) Please set toggle SW2 (AK4141) to “H”.
(5) Please write register of AK4141 with control software.
The following is register setting from the initial state of AK4141.
01H : MCKE bit & MCKD bit “0” → “1” (MCKO output for AK4682 : MCKO=256fs)
(6) Please supply SIF signal from J1 (SIF1).
(7) Please write register of AK4141 with control software.
41H : ASD bit = “0” → “1”. (Automatic system detection ON)
