Description
PHY
RXP[1:8]
Analog
Differential inputs (receive) for connection to media (transformer or fiber module)
RXM[1:8]
TXP[1:8]
Analog
Differential outputs (transmit) for connection to media (transformer or fiber module)
TXM[1:8]
FXSD[1:8]
H
Fiber signal detect – connect to fiber signal detect output on fiber module with
appropriate voltage divider if needed. Tie low for copper mode.
ISET
Analog
Transmit Current Set. Connecting an external reference resistor to set transmitter
output current. This pin connects to a 3K
1% resistor to ground if a transformer with
1:1 turn ratio is used.

L
Output (after reset)
Mode 0: Speed (on = 100/off = 10)
Mode 1: 10/100 + link + activity
10Mb link activity = slow blink (non-periodic blinking)
100Mb link activity = fast blink (non-periodic blinking)
Mode 2: Collision (on = collision/off = no collision)
Mode 3: Speed (on = 100/off = 10)
