I/O
Description
O/D Port 1 Link / Active LED
It is the combined LED of link and carrier sense signal
of the internal PHY1
O/D
Port 1 Speed LED
Its low output indicates that the internal PHY1 is
operated in 100M/S, or it is floating for the 10M mode of
the internal PHY1
O/D
Port 1 Full-duplex LED
Its low output indicates that the internal PHY1 is
operated in full-duplex mode, or it is floating for the
half-duplex mode of the internal PHY1
O/D
Port 0 Link / Active LED
It is the combined LED of link and carrier sense signal
of the internal PHY0
O/D
Port 0 Speed LED
Its low output indicates that the internal PHY0 is
operated in 100M/S, or it is floating for the 10M mode of
the internal PHY0
O/D
Port 0 Full-duplex LED
Its low output indicates that the internal PHY0 is
operated in full-duplex mode, or it is floating for the
half-duplex mode of the internal PHY0

I/O
Description
I Crystal 25MHz In
O Crystal 25MHz Out
I External system clock source
If strap pin EECS is pulled high, this pin is used for
DM9103 system clock. The frequency range is
between 20MHz and 100MHz depend on application.
