ASAHI KASEI [AKD4386] AKD4386 Evaluation board Rev.A for AK4386 GENERAL DESCRIPTION The AKD4386 is an evaluation board for the AK4386, the 24bit, 96kHz D/A converter for portable audio and home audio systems. The AKD4386 has the interface with AKM's A/D converter evaluation boards. Therefore, it is easy to evaluate the AK4386. The AKD4386 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD4386 --Evaluation board for AK4386 FUNCTION * Compatible with 2 types of interface - Direct interface with AKM's A/D converter evaluation boards - On-board AK4112B as DIR which accepts optical * BNC connector for an external clock input +5V Regulator 3V VDD VSS OPT In AK4112B (DIR) LOUT AK4386 ROUT Clock Generator DSP Data 10pin Header Figure 1. AKD4386 Block Diagram * Circuit diagram and PCB layout are attached at the end of this manual. 2005/10 ASAHI KASEI [AKD4386] Operation sequence 1) Set up the power supply lines. [VDD] (red) = 2.2 3.6V (typ. 3.0V, for VDD pin) [D3V] (red) = 2.2 3.6V (typ. 3.0V, for 74LVC541) [+5V] (orange) = 5V (for regulator) [VCC] (red) = 3.3V (for digital logic) [AGND] (black) = 0V [DGND] (black) = 0V Each supply line should be distributed from the power supply unit. 2) Set-up the evaluation modes, jumper pins and DIP switches (See the followings.) 3) Power on. The AK4386 should be reset once bringing SW2 "L" upon power-up. Evaluation mode 1) DIR (Optical Link) JP5 MCLK JP6 BICK JP7 SDTI JP8 LRCK JP13 EXT DIR EXT DIR EXT DIR EXT 2) Using AKM's evaluation board for ADC To evaluate the AK4386 with analog input, the AKM's evaluation board for ADC can be used. MCLK, BICK and LRCK and A/D converted data are sent to the AKD4386 through PORT1 (DSP) via 10pin flat cable.
