STE10A Datasheet, PDF (6/82 Pages) STMicroelectronics – PCI 10/100 Ethernet controller with integrated PHY (3.3V)

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
STE10/100A evaluation board schematics for details)
