ASAHI KASEI [AKD4120] AKD4120 AK4120 Evaluation Board Rev.A GENERAL DESCRIPTION The AKD4120 is an evaluation board for the AK4120, digital sample rate converter with mixer and volume. The AKD4120 has the interface with AKM’s D/A and A/D converter to evaluation boards. Therefore, it is easy to evaluate the AK4120 via analog output. This has also optical connector to interface with other digital audio equipment. Ordering guide AKD4120 --- AK4120 Evaluation Board (Cable for connecting with printer port of IBM-AT compatible PC and control software are packed with this.) FUNCTION • Compatible with 2 types of interface - Optical interface by AK4112B (DIR) and AK4114 (DIT & DIR) - Direct interface with AKM’s DAC & ADC evaluation boards by 10pin headers. • BNC connectors for an external clock input • 10pin headers for the serial control data interface GND 3.3V 5V AK4114 AK4112B Optical Input (DIR) Input#1 Output (DIT,DIR) 10pin Header Audio Data Input#2 Optical Input (PORT5) Optical Output 10pin Header Audio Data Input 10pin Header AK4120 10pin Header Audio Data Output Register Control Figure 1.

Open : 3.3V is supplied from VCC-3V. 2.Set up power supply lines VCC= 5V VCC-3V= 3.3V 3V-1= 3.3V GND= 0V : Power supply for TVDD of the AK4112B and AK4114, and for logic circuit. : This jack is used when VDD of the AK4120 is supply from this. In this case, JP11 should be open. : Power supply for logic, the AK4112B and the AK4114. In this case, JP11 should be short and notihg should be connected to VCC-3V. : This is ground for all regions in this board. 3. Set up the evaluation modes by jumper pins and DIP switches. (See the next section.) 4. Power on. The AK4120 should be reset once by bringing SW2 “L” upon power-up. The AK4120 is reset at SW2= “L” and exits resetting at SW2= “H”. When SW2 = “L”, the internal registers cannot be written. <KM066802> 2006/12 -2- ASAHI KASEI [AKD4120] Evaluation mode The AK4120 has four path modes that interface between two input ports and one output port. Four audio data formats can be selected independently for each port. Input#1 port supports only slave mode. Input#2 port and output port support slave mode and master mode. This evaluation board, AKD4120 has a standard optical interface via DIR/DIT and AKM original 10pin interface for AKM’s AD/DA evaluation board. The AKD4120 can select either optical interface or 10pin interface for each port. Set the evaluation mode by the following operation sequence. 1) 2) 3) 1. Control I/F mode Path mode and Clock mode Audio data format Control I/F mode Control I/F mode is set by JP14 and S1. Attached control software is written for using 3-wire serial and Chip Address CAD1, CAD0 (CAD1, CAD0 = ”10”). See the section of “DIP switch setup” and “Jumper list”. Set-up of JP14 and S1 is shown below.

Therefore, it is not needed to set up CAD1 pin. <KM066802> 2006/12 -3- ASAHI KASEI [AKD4120] 2. Path mode and Clock mode 2-1.

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. <KM066802> 2006/12 -
