Figure 6. Consumer Input Circuit (Coaxial Input)
Note 1: In case of coaxial input, if a coupling level to this input from the next RX input line
pattern exceeds 50mV, there is a possibility to occur an incorrect operation. In this
case, it is possible to lower the coupling level by adding this decoupling capacitor.
Note 2: Ground of RCA connector and terminator should be connected to PVSS of the
AK4586 with low impedance on PC board.

Figure 7. Consumer Input Circuit (Optical Input)
In case of coaxial input, as the input level of RX line is small, be careful not to crosstalk among RX input lines. For
example, by inserting the shield pattern among them.
The AK4586 includes the TX output buffer. The output level meets combination 0.5V+/-20% using the external resistor
network. The T1 in Figure 8 is a transformer of 1:1.
