AKD4114-B
AK4114 Evaluation Board Rev.0
GENERAL DESCRIPTION
AKD4114-B is the evaluation board for AK4114, 192kHz digital audio transceiver. This board has optical
and BNC connector to interface with other digital audio equipment.
Ordering guide
AKD4114-B
--- Evaluation board for AK4114
(A cable for connecting with printer port of IBM-AT compatible PC
and a control software are packed with this. The control software
does not operate on Windows NT.)

S/PDIF
MCLK, BICK, LRCK and DAUX are input the via 10pin header (PORT2: DIR). The AKD4114-B can be
connected with the AKM’s DAC evaluation board via 10-line cable.
a. Set-up of a Bi-phase output signal
TX0 and TX1 should not select an optical connector or a BNC connector at the same time.
a-1. The data outputted from TX1 can be selected by OPS12-10 bit.

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 AK4114, 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
becomes “H” or “1”. If not, “L” or “0”.
If you want to write the input data to AK4114, 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.
