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 control mode, two channel
inputs (RX1 and RX5) are available, RX2, RX3, RX4 and RX6 change to other pins for mode settings. Those pins must
be fixed to “H” or “L” because they are not normal logic input.
The AK4113 includes the TX output buffer. The output level meets combination 0.5V± 20% using the external resistor
network. The T1 in Figure 19 is a transformer of 1:1.

Bi-phase signal input/output circuit
Note: For coaxial input, if a coupling level to this input from the next RX input line pattern
DVSS
exceeds 50mV, there may be an incorrect operation. In this case, it is possible to
lower the coupling level by adding this decoupling capacitor.
