Address.
Sets device address.
Twisted-Pair/Fiber Outputs, Positive and Negative.
During 100BASE-TX or 10BASE-T operation, TPFOP/N pins drive
IEEE 802.3 compliant pulses onto the line.
During 100BASE-FX operation, TPFOP/N pins produce differential
LVPECL outputs for fiber transceivers.
Twisted-Pair/Fiber Inputs, Positive and Negative.
During 100BASE-TX or 10BASE-T operation, TPFIP/N pins receive
differential 100BASE-TX or 10BASE-T signals from the line.
During 100BASE-FX operation, TPFIP/N pins receive differential
LVPECL inputs from fiber transceivers.
Signal Detect / Twisted Pair.
SD/TP_L acts as a dual-function input, depending on the LXT971A
Transceiver mode.
Normal, Reset, and Power-Up Operations.
“Normal” operation is operation other than reset or power-up. In
either reset or power-up, SD/TP_L is used to select one of the two
following media modes.
Twisted-Pair Mode.
For normal operation that uses the twisted-pair mode, connect SD/
TP_L to ground.
Fiber Mode.
For normal operation that uses the fiber mode, SD/TP_L acts as the
SD input from the fiber transceiver.
• Twisted-pair mode - Connect SD/TP_L Low
• Fiber mode - Connect SD/TP_L High (Register bit 16.0 = 1).
(Register bit 16.0 = 0).
