mode 0 = Link and traffic LED. Active low to indicate normal

link, and it will flash as a traffic LED when transmitting or

receiving.

mode 1 = traffic LED only

FDX#

O/D

LED Output Pin, Active Low

mode 0 = Full duplex LED

mode 1 = Full duplex LED

SPD100#

O/D

LED Output Pin, Active Low

mode 0 = 100Mbps LED

mode 1 = 100Mbps LED

SPD10#

O/D

LED Output Pin, Active Low

mode 0 = 10Mbps LED

mode 1 = Link LED

5.4 Network Interface

Description

105,106

RXI+

RX-

100M/10Mbps Differential Input Pair.

These two pins are differential receive input pair for

100BASE-TX and 10BASE-T. They are capable of receiving

100BASE-TX MLT-3 or 10BASE-T Manchester encoded

data.

109,110

TXO+

TXO-

100M/10Mbps differential output pair.

These two pins are differential output pair for 100BASE-TX

and 10BASE-T. This output pair provides controlled rising and

falling time, designed to filter the transmitter’s output.

5.5 Miscellaneous Pins

Pin No.

128LQFP

Pin Name

I/O

Description

IDSEL2

PCI IDSEL 2.

When this pin is pulled high, the PCI multiple function is

present, and it act as PCI IDSEL2 function.

REQ2#

PCI Request 2

If the PCI multiple function mode is selected, this pin act as the

PCI REQ2# function.

GNT2#

PCI GNT2#

If the PCI multiple function mode is selected, this pin act as

GNT2# function.

When this pin is pulled high, the DM9102D is in LED mode 1

otherwise the led mode 0 is selected.

CLOCKRUN#

I/O

Clockrun#

The clockrun# signal is used by the system to pause or slow

down the PCI clock signal. It is used by the DM9102D to

enable or disable suspension or restart of the PCI clock. When

the CLOCKRUN# pin is not used, this pin should be connected

to an external pulled down resistor.

TEST2

TEST mode control 2

In normal operation, tie high to this pin.
