BI-PHASE SIGNAL INPUT CIRCUITS (RX0, RX1, RX2)
If RX1, which has a built-in amplifier, is used as a coaxial input signal corruption may occur due to
the influence of the adjacent RX0 and RX2 input pins. RX0 and RX2 should be fixed to Low to
prevent them from influencing RX1.
The input signal to RX1 is temporarily open if RX1 is selected. The RX0 and RX2 potential must be
fixed due to coupling effects. In this case, 5 bi-phase signal input pins can be selected; RX1 and RX3
to RX 6.
If the input signal to RX1 is absolutely fixed to either High or Low then all 7 input pins can be used.
