[VA] (orange) = 2.2 ∼ 3.3V [D2V] (orange) = 1.8 ∼ 3.3V [VCC] (red) = 3.6 ∼ 5.0V [AGND] (black) = 0V [DGND] (black) = 0V : for VA of AK5354 (typ. 2.5V) : for D2V of 74LVC541 (typ. 2.5V) : for logic : for analog ground (including VSS of AK5354) : for logic ground Each supply line should be distributed from the power supply unit. D2V and VA must be same voltage level. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) Note : Evaluation mode of the AK5354 is fixed to I2S compatible on the board. 3) Power on. The AK5354 and AK4353 should be reset once bringing SW1 = SW2 = “L” upon power-up. n Evaluation mode Applicable Evaluation Mode (1) Evaluation of A/D using DIT (Optical Link) (2) Evaluation of A/D using D/A converted data (3) All interface signals including master clock are fed externally. (1) Evaluation of A/D using DIT (Optical Link) PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX176). It is possible to connect AKM’s D/A converter evaluation boards on the digitalamplifier which equips DIR input. Nothing should be connected to PORT3 (ROM). In case of using external clock through a BNC connector (J3), select EXT on JP6 (CLK) and short JP5 (XTE) and open JP7 (EXT). JP5 JP6 CLK XTE XTL JP7 EXT EXT (2) Evaluation of A/D using D/A converted data It is possible to make evaluation in the form of analog inputs and analog outputs by interfacing with various AKM’s D/A evaluation boards with PORT3 (ROM). JP5 XTE JP6 CLK XTL JP7 EXT EXT <KM062600> ’00/06 -3- ASAHI KASEI [AKD5354] (3) All interface signals including master clock are fed externally. Under the following set-up, all external signals needed for the AK5354 to operate could be fed through PORT3 (ROM). JP5 XTE JP7 JP6 CLK XTL EXT EXT n The function of the toggle SW Upper-side is “H” and lower-side is “L”. [SW1] (PDN): Resets the AK5354. Keep “H” during normal operation. [SW2] (DIT): Resets the AK4353. Keep “H” during normal operation. n Serial Control The AK5354 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT2(CTRL) with PC by 10-line flat cable packed with the AKD5354. Take care of the direction of connector. There is a mark pin#1 to connector.
