Speed LED
It’s low output indicates that the internal PHY is operated in 100M speed,
or it is floating for the 10M mode of the internal PHY.
Full-duplex LED
In LED mode 1, It’s low output indicates that the internal PHY is operated
in full-duplex mode, or it is floating for the half-duplex mode of the
internal PHY.
In LED mode 0, It’s low output indicates that the internal PHY is operated
in 10M mode, or it is floating for the 100M mode of the internal PHY.
Link LED
In LED mode 1, it is the combined LED of link and carrier sense signal of
the internal PHY.
In LED mode 0, it is the LED of the carrier sense signal of the internal
PHY only.
Fiber-optic Signal Detect
PECL signal indicates whether or not the fiber-optic receives pair is
receiving valid levels.
Bandgap Ground.
