Programmable option pins are grouped center left. The PAUI pin is tied Low and all other option
pins are tied High. This set-up selects the following options:
Status outputs are grouped at lower left. Local status outputs drive LED indicators and remote
status indicators are available as required.
Power and ground pins are shown at the bottom of the diagram. A single power supply is used for
both VCC1 and VCC2 with a decoupling capacitor installed between the power and ground busses.
The twisted-pair and AUI interfaces are shown at upper and lower right, respectively. Impedance
matching resistors for 100 UTP are installed in each I/O pair but no external filters are required.
