Note: For coaxial input, if a coupling level to this input from the next RX input line
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.

Note. When RXN pin is unused, RXN pin must be AC-coupled to ground.
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”.
