The NWK954 is a fully integrated, unmanaged, 4-port Fast
Ethernet Repeater conforming to the IEEE 802.3 100BASE-TX
Standard. The device integrates the 802.3 Repeater functions
with four 100BASE-TX PHY modules, enabling direct connection
to the isolation transformers with no additional PHY components.
It has built-in LED drivers for display of port activity and
network utilization. There is a local expansion port which allows
up to six NWK954s to be cascaded to form a 24-port repeater
with no additional components.
With the addition of simple backplane driver/receivers, up to
eight 24-port repeaters can be stacked.
The NWK954 is supplied in a 128-pin PQFP and interfaces
to the twisted pair media through 1:1 isolation transformers.
