Activity LED. The Activity LED pin indicates either transmit or receive
activity. When activity is present, the activity LED is on; when no
activity is present, the activity LED is off.
In Wake on LAN mode, the ACTLED# signal is used to indicate that
the received frame passed MAC address filtering.
Link Integrity LED. The Link Integrity LED pin indicates link integrity.
If the link is valid in either 10 or 100 Mbps, the LED is on; if link is
invalid, the LED is off.
Speed LED. The Speed LED pin indicates the speed. The speed LED
will be on at 100 Mbps and off at 10 Mbps.
Reference Bias Resistor (100 Mbps). This pin should be connected
to a 649 Ω pull-down resistor.
Reference Bias Resistor (10 Mbps). This pin should be connected
to a 619 Ω pull-down resistor.
Voltage Reference. This pin is connected to a 1.25 V ± 1% external
voltage reference generator. To use the internal voltage reference
source, this pin should be left floating. Under normal circumstances,
the internal voltage reference should be used and this pin would be left
open.
