AKD4101A-B
AK4101A Evaluation Board Rev.0
GENERAL DESCRIPTION The AKD4101A-B is an evaluation board for the AK4101A, 192kHz DIT. The AKD4101A-B has the interface with AKM's A/D converter evaluation boards and AKM's DIR evaluation boards. Therefore, it is easy to evaluate the AK4101A. The AKD4101A-B also has the digital audio interface and can achieve the interface with digital audio systems via optical link, BNC unbalance or XLR balance connector. Ordering guide
AKD4101A-B --Evaluation board for AK4101A (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.)
FUNCTION Digital interface Compatible with 2 types of interface - Direct interface with AKM's ADC, DIR evaluation boards by 10pin header - Optical/BNC/XLR output Serial control data I/F - 1 input/output port (10-pin port)

B, C, U, V Inputs (synchronous mode)
At synchronous mode (ANS=1), C(channel status), U(user data) and V(validity) are input via 10pin header (PORT3: BCUV). BLS is output at normal mode (TRANS=0), and is input at audio routing mode (TRANS=1). In case of audio routing mode, BLS, C, U an V can be directly input from the AKD4114 via 10-line flat cable. The pin layout of PORT3 is shown in Figure 2.

Serial control
The AK4101A can be controlled by pins at synchronous mode (ANS=1) and by internal register at asynchronous mode (ANS=0). Synchronous/Asynchronous mode is set as Table 7. Mode Synchronous Asynchronous SW1-6 (ANS) JP18 (SDA/CDTO) FS3=1: Short "CDTO/CM0=H" side. ON FS3=0: Short "CM0=L" side. OFF Short "CDTO/CM0=H" side. Table 7. Synchronous/Asynchronous mode Sub_JP20 (ANS) Open. Short. Default
At asynchronous mode (ANS=0), the AK4101A can be controlled via printer port (parallel port) of IBM-AT compatible PC. Connect PORT6 (uP-I/F) with PC by 10-line flat cable packed with the AKD4101A-B. Take care of the direction of connector. There is a mark at pin#1. The pin layout of PORT6 is shown in Figure 3.
