Digital Power
Digital Ground
Active low to reset the internal logic of DM9081. It should be
synchronized to X2 if multiple DM9081s
These two pins are used to select LED display mode. Normal mode is
selected if both pins are connected to V
if both pins are connected to GND. Other settings are prohibited
These pins should be left open
A 20MHz oscillator or crystal should be attached to this pin
This pin is used in crystal connection only. It is left open when using an
oscillator
Analog Power
Analog Ground
This pin is used to latch the serial LED information from pins 6 to 13
In minimum mode, this pin sends out TP7 Link and Carrier Sense
status
This pin transmits AUI port status synchronous to TCK
In minimum mode, this pin sends out TP6 Link and Carrier Sense
status
This pin sends out global bit rate error status of the DM9081 Hub
In minimum mode, this pin sends out TP5 Link and Carrier Sense
status
In minimum mode, this pin sends out TP4 Link and Carrier Sense
status
This pin transmits global jabber status of the DM9081 Hub
In minimum mode, this pin sends out TP3 Link and Carrier Sense
status
This pin sends out utilization of 10MHz bandwidth synchronous to TCK
In minimum mode, this pin sends out TP2 Link and Carrier Sense
status
This pin sends out the partition status synchronous to TCK for the eight
TP ports
In minimum mode, this pin sends out TP1 Link and Carrier Sense
status
This pin sends out the link and carrier sense status synchronous to
TCK for the eight TP ports
In minimum mode, this pin sends out TP0 Link and Carrier Sense
status
Active low for 52ms when AUI Port 1 detects carrier
Active low for 52ms when AUI Port 2 detects carrier
Active low for 26ms when collision is detected
A 10MHz clock synchronous to X2
are used
