NOTE
1 Symbols lih and lil shows the signal flow direction, + signals
flow into the receiver, and – signals flow out of the receiver.
2 When the input voltage is low level, high–speed skip signals
are regarded as logic “1”, and when the input voltage is high
level, the signals are regarded as logic “0”.
