Electrical aspects common for both solutions 28/108
Note:
The device supports the Auto-Crossover function. Due to this fact,
the signals RX and TX may be exchanged.
The following assignment of pins and signals has been made:
Pin Channel Ethernet
Signal Description
46 Ethernet
Channel 0 Ethernet receive line of Port 0.
47 Ethernet
Channel 0 PHY0_TX-
48 Ethernet
Channel 0 Ethernet transmit line of Port 0
49 Ethernet
Channel 0 PHY0_RX-
42 Ethernet
Channel 0 MLED2 This signal controls the Link LED of Ethernet Port
0. The signal is active low and has to be
connected at the cathode of the LED over an
appropriate current resistor.
42 Ethernet
Channel 0 MLED2 This signal controls the Transmit/Receive or
Activity LED of Ethernet Port 0. The signal is
active low and has to be connected at the cathode
of the LED over an appropriate current resistor.
50 Ethernet
Channel 1 Ethernet receive line of Port 1.
51 Ethernet
Channel 1 PHY1_TX-
52 Ethernet
Channel 1 Ethernet transmit line of Port 1
53 Ethernet
Channel 1 TXN1/
PHY1_RX-
43 Ethernet
Channel 1 MLED3 This signal controls the Link LED of Ethernet Port
1. The signal is active low and has to be
connected at cathode of the LED over an
appropriate current resistor.
43 Ethernet
Channel 1 MLED3 This signal controls the Transmit/Receive or
Activity LED of Ethernet Port 1. The signal is
active low and has to be connected at cathode of
the LED over an appropriate current resistor.
