INTRODUCTION TO DEMO
This DEMO board uses 5VDC power supply.
When the 5VDC power supply is inserted in the lower left of Figure 1, the green LED in the upper left corner lights up.
Support two kinds of SPDIF signal interface, respectively coaxial signal and optical fiber signal.
The upper yellow RCA interface (J1) in Figure 1 is the SPDIF coaxial input.
The black interface (J2) in the upper right of Figure 1 is the SPDIF fiber input.
This module automatically recognizes the inserted signal source, but when two signals are input simultaneously, an exception will occur.
Analog stereo is output from the lower RCA, white is the left channel, and red is the right channel.
