ASAHI KASEI
For coaxial input in serial mode, the input level of RX line is small, so care must be taken to avoid crosstalk among the
RX input lines. In this case, a shield is recommended between the input lines. In parallel mode, RX3-0 is available and
RX7-4 change to other pins for audio format control. Those pins must be fixed to “H” or “L”.

pattern exceeds 50mV, there may be an incorrect operation. In this case, it is
possible to lower the coupling level by adding this decoupling capacitor.
