Figure 2. AKD7782-A Board Diagram
(1) AIN/DAC (RCA Jack)
AIN: Analog input jacks. DAC: Analog output jacks.
The white jacks are used for left channel and the red ones are for right channel.
(2) AK4118A
AK4118A has DIR, DIT and X’tal oscillator. It transports digital data to AK7782 when working in master mode and
outputs data from AK7782 when working in slave mode.
(3) SPDIF-IN/SPDIF-OUT (Optical Connector)
SPDIF-IN (input): It inputs optical digital signal to AK4118A and supports sampling frequencies from 8 to 96kHz.
SPDIF-OUT (output): It outputs optical digital signal from AK4118A and supports sampling frequencies from 8 to
96kHz.
(4) +12V/GND (Power supply)
Connect to +12V and GND according to the following operation sequence on page 4.
(5) PIC18F4550
USB control chip. It is possible to set up the registers of AK7782, FPGA and AK4118A from PC via USB port.
(6) SW1
Push type switch. It is used to initialize PIC18F4550. Please push down the button once when PC has trouble
identifying the evaluation board.
