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

EVALUATION BOARD MANUAL Operation sequence
1.Set up the jumper for power supply [JP11 (D3V) ] Select power supply for VDD pin of the AK4120 Short : 3.3V is supplied from 3V-1 jack (Default) Notihg should be connected to VCC-3V. Open : 3.3V is supplied from VCC-3V. 2.Set up power supply lines VCC= 5V VCC-3V= 3.3V 3V-1= 3.3V
: 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.
GND= 0V
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.

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)

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. Jumper No. DIP switch No. JP14 S1: No.4 S1: No.5 Set-up CSN OFF OFF
