ASAHI KASEI [AKD5366] AKD5366 Evaluation board Rev.A for AK5366 GENERAL DESCRIPTION AKD5366 is an evaluation board for the digital audio 24bit 48kHz A/D converter, AK5366. The AKD5366 includes the input circuit and also has a digital interface transmitter. Further, the AKD5366 can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD5366 --Evaluation board for AK5366 (Cable for connecting with printer port of IBM-AT, compatible PC and control software are packed with this.)

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).
