When using coaxial input, the input level of the RX line is small. Care must be taken to reduce, crosstalk among RX input
lines by inserting a shield pattern between them.

Biphase Signal Input Circuit
Note 19. Coaxial input only : if a coupling level to this input by the next RX input line pattern exceeds 50mV,
Note 20. Ground of the RCA connector and terminator should be connected to AVSS of the AK4122A with low
an malfunction may occur. In this case, it is possible to lower the coupling level by adding this
decoupling capacitor.
