Electrical Specifications
Notes:
1.
Used during initialization. It is the state of “OFF” condition for the transmitter. That is, when the output driver is disconnected
and only the minimum termination is connected. The link detection resistor is assumed not connected when specifying this
parameter.
2.
Used during initialization. It is the state of “OFF” condition for the receiver when only the minimum termination is connected.
