Evaluation Board Manual Operation sequence 1) Set up the power supply lines. [AVDD] (red) = 4.75 ∼ 5.25V [TVDD] (orange) = 3.0 ∼ 5.25V [D3V] (orange) = 3.0 ∼ 5.25V [VCC] (red) = 5V [AGND] (black) = 0V [DGND] (black) = 0V : for AVDD of AK5366 (typ. 5.0V) : for DVDD of AK5366 (typ. 3.3V) : for 74LVC541 (typ. 3.3V) : for logic : for analog ground : for logic ground Each supply line should be distributed from the power supply unit. D3V and TVDD must be same voltage level. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) 3) Power on. The AK5366 and AK4103 should be reset once bringing SW2 = “L” upon power-up. Evaluation mode (1) Slave Mode When evaluating the AK5366 using the AK4103, the setting of the AK5366’s audio interface format should be the same as the AK4103’s format. The DIF setting of the AK5366 (No.1 of SW1 (I2C) in parallel mode, DIF bit in serial mode) should be the same as the DIF setting of the AK4103 (No.1 of SW3). About the AK5366’s audio interface format, refer to AK5366’s datasheet. About the AK4103’s audio interface format, see Table3. (1-1) A/D evaluation using DIT function of AK4103 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 digital-amplifier which equips DIR input. Nothing should be connected to PORT2 (ROM). In case of using external clock through a BNC connector (J13), select EXT on JP8 (CLK) and short JP6 (XTE) and open JP9 (EXT).

As used here: (a) A hazard related device or system is one designed or intended for life support or maintenance of safety or for applications in medicine, aerospace, nuclear energy, or other fields, in which its failure to function or perform may reasonably be expected to result in loss of life or in significant injury or damage to person or property. (b) A critical component is one whose failure to function or perform may reasonably be expected to result, whether directly or indirectly, in the loss of the safety or effectiveness of the device or system containing it, and which must therefore meet very high standards of performance and reliability. • It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or otherwise places the product with a third party to notify that party in advance of the above content and conditions, and the buyer or distributor agrees to assume any and all responsibility and liability for and hold AKM harmless from any and all claims arising from the use of said product in the absence of such notification. <KM073600> 2004/05 -
