asahi kasei [akd4643-b] 2005/12 - 2 - evaluation board manual ? operation sequence 1) set up the power supply lines. [vcc] (red) = 5.0v (or 3.3v) [agnd] (black) = 0v [dgnd] (black) = 0v each supply line should be distri buted from the power supply unit. when the power is supplied to the AK4643 via the regulator, jp21 should be set to ?reg? side and vcc should be 5.0v. (when the power is supplie d from vcc jack to the AK4643 directly, jp21 should be set to ?vcc? side and vcc should be 3.3v.) 2) set up the evaluation mode, jumper pins. (see the followings.) 3) power on. the AK4643 and ak4114 should be reset once bringing sw1 ?l? upon power-up. and the ak7830 should be reset once bringing sw2(spk_pdn) ?l? upon power-up. ? evaluation mode (1) slave mode (1-1) evaluation of recording block (mic, adc) using dit of ak4114 (1-2) evaluation of playback block (hp, spk, lout) using dir of ak4114 (1-3) evaluation of loop-back using ak4114 (1-4) all interface signals including master clock are fed externally. the ak4114?s audio interface format is fixed to i 2 s compatible. (1-1) evaluation of recording block using dit of ak4114 port2 (dit) and x1 (x?tal) are used. dit generates audio bi-phase signal from received data and which is output through optical connector (totx141). nothing should be connected to port1 (dir) and port3 (dsp). jp6 bick2 jp7 lrck2 jp11 sdti ad c dir jp8 lrck jp9 mclk jp10 bick (1-2) evaluation of playback block usi ng dir of ak4114 port1 (dir) is used. nothing should be connected to port3 (dsp). jp6 bick2 jp7 lrck2 jp11 sdti ad c dir jp8 lrck jp9 mclk jp10 bick the ak4114 operates at fs of 32khz or mo re. if the fs is slower than 32khz, any other evaluation mode without using dir should be used.
