asahi kasei [AKD5358-b] 2005/09 - 2 - 1. evaluation board manual ? operation sequence 1) set up the power supply lines. [va] (red) = 2.7 5.5v or +15v : for va of ak5358 (typ. 5.0v) [vd] (orange) = 2.7 5.5v : for vd of ak5358, 74hc14 (typ. 5.0v) [vcc] (red) = 3.3v : for ak4114 [agnd] (black) = 0v : for analog ground [dgnd] (black) = 0v : for logic ground each supply line should be distributed from the power supply unit. 2) set up the evaluation mode, jumper pins and dip switches. (see the followings.) 3) power on. the ak5358 and ak4114 should be reset once bringing sw2 = ?l? upon power-up. ? evaluation mode (1) slave mode (1-1) a/d evaluation using dit function of ak4114 port2 (dit) is used. dit generate s audio bi-phase signal from receive d data and which is output through optical connector (totx141). it is possible to connect akm?s d/a converter evaluation boards on the digital-amplifier, which equips dir input. nothing should be connected to port1 (dsp). jp5 mclk (1-2) all interface signals including master clock are fed externally. port1 (dsp) is used. all interface signals (mcl k, sclk, lrck) are provided to the ak5358 through port1. jp5 (mclk) should be open. the dif1 of sw1 (mode) should be set to ?h?. jp5 mclk
asahi kasei [AKD5358-b] 2005/09 - 3 - (2) master mode (2-1) a/d evaluation using dit function of ak4114 port2 (dit) is used. dit generate s audio bi-phase signal from receive d data and which is output through optical connector (totx141). it is possible to connect akm?s d/a converter evaluation boards on the digital-amplifier, which equips dir input. nothing should be connected to port1 (dsp). the dif1 of sw1 (mode) should be set to ?h?. jp5 mclk (2-2) master clock is fed externally. port1 (dsp) is used. mclk is provided to the ak5358 through port1. jp5 (mclk) should be open. the dif1 of sw1 (mode) should be set to ?h?. jp5 mclk ? other jumper pins set up 1. jp1 (gnd) : analog ground and digital ground open : separated. short : common. (the connector ?dgnd? can be open.) 2. jp2 (cks1) : setting of cks1 pin for ak5358 h : master mode l : slave mode 3. jp3 (va) : select va for ak5358 va : supply from va connector reg : supply from regulator. va connector should be supplied +15v. 4. jp4 (vd) : select vd for ak5358 va : supply from va connector vd : supply from vd connector
