Overview

STE10/100A

LED display

● Provides 2 LED display modes:

– 3 LED displays for

100Mbps (on) or 10Mbps (off) link (remains on when link ok) or activity (Blinks at

10Hz when receiving or transmitting collision-free) FD (Remains on when in full

duplex mode) or when collision detected (Blinks at 20Hz)

– 4 LED displays for:

100 link (On when 100M link ok)

10 link (On when 10M link ok)

Activity (Blinks at 10Hz when receiving or transmitting)

FD (Remains on when in full duplex mode) or when collision detected (Blinks at

20Hz)

● If no LED is used, then: Pull the pins 90, 91, 92 of U4 to high with 4.7K resistor (see
