connector and BNC connector to interface with other digital audio equipment. Figure 1. AKD4117-B Block Diagram *Circuit diagram and PCB layout are attached at the end of this manual.

(1) Set up the power supply lines. The AK4117 should be reset once bringing PDN(SW2) “L” upon power-up. evaluation board via 10-line cable. RX0 and RX1 should not select BNC at the same time. Table 1. Set-up of RX0 When S/PDIF signal is inputted from PORT1 (optical), JP19 should be short. a-2. RX1 can be inputted from a BNC (J2) connector only. Table 2. Set-up of RX1

Table 3. Recovery Data Select The signal level outputted/inputted from PORT2 is 3.3V. Figure 2. PORT2 pin layout low power mode, PLL lock range is up to 48kHz and the MCKO frequency is fixed to 256fs. selects the ratio (x1 or x1/2) of the MCKO frequency to the X’tal frequency (Table 5). Table 4. Master Clock Frequency Select Table 5. Master Clock Frequency Select

Table 6. Audio format The operation mode of PLL is selected by CM1 and CM0. It can be selected by CM1-0 bits. Note: When the X’tal is not used as clock comparison for fs detection (XTL0, 1= “1,1”), the X’tal is OFF. Table 7. Clock Operation Mode Select

U(user data) can be monitored by TP1: U. is a mark at pin#1. The pin layout of PORT6 is as Figure 3. Figure 3. PORT6 pin layout

[AKD4117-B] <KM077200> - 7 - Control Software Manual „ Set-up of evaluation board and control software 1. Set up the AKD4117-B according to previous term. 2. Connect IBM-AT compatible PC with AKD4117-B by 10-line type flat cable (packed with AKD4117-B). Take care of the direction of 10pin header. (Please install the driver in the CD-ROM when this control software is used on Windows 2000/XP. Please refer “Installation Manual of Control Software Driver by AKM device control software”. In case of Windows95/98/ME, this installation is not needed. This control software does not operate on Windows NT.) 3. Insert the CD-ROM labeled “AKD4117-B Evaluation Kit” into the CD-ROM drive. 4. Access the CD-ROM drive and double-click the icon of “akd4117-b0.exe” to set up the control program. 5. Then please evaluate according to the follows. „ Operation flow Keep the following flow. 1. Set up the control program according to explanation above. 2. Click “Write default” button. 3. Then set up the dialog and input data. „ Explanation of each buttons 1. [Port Setup] : Set up the printer port. 2. [Write default] : Initialize the register of AK4117. 3. [All Write] : Write all registers that is currently displayed. 4. [Read All] : All the registers of AK4117 are read. 5. [Function1] : Dialog to write data by keyboard operation. 6. [F3] : Dialog of sequential writing. 7. [SAVE] : Save the current register setting. 8. [OPEN] : Write the saved values to all register. 9. [Write] : Dialog to write data by mouse operation. 10. [Read] : The data corresponding to each register is read.

[AKD4117-B] <KM077200> - 8 - „ Explanation of each dialog 1. [Function1 Dialog] : Dialog to write data by keyboard operation Address Box: Input register address in 2 figures of hexadecimal. Data Box: Input register data in 2 figures of hexadecimal. If you want to write the input data to AK4117, click “OK” button. If not, click “Cancel” button. 2. [Write Dialog] : Dialog to write data by mouse operation There are dialogs corresponding to each register. Click the “Write” button corresponding to each register to set up the dialog. If you check the check box, data If you want to write the input data to AK4117, click “OK” button. If not, click “Cancel” button. „ Indication of data Input data is indicated on the register map. Red letter indicates “H” or “1” and blue one indicates “L” or “0”. Blank is the part that is not defined in the datasheet. „ Attention on the operation If you set up Function1 dialog, input data to all boxes. Attention dialog is indicated if you input data or address that is not specified in the datasheet or you click “OK” button before you input data. In that case set up the dialog and input data once more again. These operations does not need if you click “Cancel” button or check the check box.
