[va] (red) = 2.7 5.5v or +15v : for va of ak5359 (typ. 5.0v) [vd] (orange) = 2.7 5.5v : for vd of ak5359, 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 distri buted from the power supply unit. 2) set up the evaluation mode, jumper pins and dip switches. (see the followings.) 3) power on. the ak5359 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 generates audio bi-phase signal from received 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 (mclk, sclk, lrck) are provided to the ak5359 through port1. jp5 (mclk) should be open. the dif1 of sw1 (mode) should be set to ?h?. jp5 mclk
