ASAHI KASEI
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.
MS0267-E-03
Biphase signal input circuit
Note 1: Coax input only : if a coupling level to this input from the next RX input line pattern exceeds 50mV,
Note 2: Ground of the RCA connector and terminator should be connected to AVSS of the AK4122 with low
an incorrect operation may occur. In this case, it is possible to lower the coupling level by adding this
decoupling capacitor.
