Evaluation Board Rev.A for AK5356
GENERAL DESCRIPTION AKD5356 is an evaluation board for the portable digital audio 20bit A/D converter with Pre-Amp and Analog Volume. The AKD5356 includes the analog input circuits (LINE and Pre-Amp) and also has a digital interface transmitter. Further, the AKD5356 can evaluate direct interface with AKM's D/A converter evaluation board. n Ordering Guide
AKD5356 --- Compatible with 2 types of interface (Cable for connecting with printer port of IBM-AT, compatible PC and control software are packed with this. This control software does not support Windows NT/2000/XP.)
FUNCTION * Compatible with 2 types of interface - Direct interface with AKM's D/A converter evaluation boards - On-board AK4103 as DIT which transmits optical output * BNC connectors for LINE / MIC inputs * BNC connectors for Pre-Amp input / output

EVALUATION BOARD MANUAL n Operation sequence
1) Set Up the power supply lines [AVDD] (Orange) = 2.0 3.3V (typ. 2.5V, AVDD pin) [DVDD] (Orange) = 1.8 AVDD (typ. 2.5V, DVDD pin, U2:74LCV541, U5:74LCV07A) [MVDD] (Green) = 2.4 3.3V (typ. 2.7V, MVDD pin) [VCC] (Red) = 5.0V (for digital logic except the AK5356) [AVSS] (Black) = 0V [DVSS] (Black) = 0V [MVSS] (Black) = 0V Each supply line should be distributed from the power supply unit. DVDD and AVDD must be the same voltage level. When the regulator (3V output) is used, "AVDD" terminal supplies "5V". 2) Set up the evaluation mode, jumper pins and DIP switches. (See the following) 3) Power on The AK5356 and AK4103 should be reset once bringing SW1 = SW3 = "L" upon power-up.

(3) Evaluation of A/D using DIT at MCLK=384fs. PORT1 (DIT) is used. On board DIT (AK4103) is set to the master mode. The AK4103 provides BICK and LRCK to the AK5356 from an external master clock (MCLK). When using an external clock through a BNC connector (J8), select "EXT" on JP11 (CLK) and short JP10 (XTE). (Refer to Table 2, Table 3 and Table 4 for the set up of the DIP switches. The master mode should be selected in Table 2. The master clock (384fs) should be selected in Table 4.)
