LED DISPLAY MATRIX

The LED Display uses refresh technique. By using the LED display matrix, the number of ports to drive the LED can be

significantly reduced. Two LEDs are assigned for each port. On, Off, and Flash states are used to indicate different

information. With reduced LED counts, and reduced number of signals, the LED display will be easier to route on the board,

and less costly.

SYSTEM CONSIDERATIONS

The design of the chip is optimized for low cost 10/100 Mb unmanaged repeater applications. It also provides flexibility for

systems that require multiple LAN ports within the same unmanaged repeater domain.
