FUNCTIONAL DESCRIPTION
Overvlew
The NWK954 is a mixed-signal CMOS device which
integrates all of the functions required for an unmanaged 4-
port 100BASE TX repeater as defined in the IEEE 802.3
Standard. The device incorporates all of the necessary
100BASE-TX PHY functions to allow direct interfacing to a
quad 1:1 magnetics module with a modest number of external
passive components. The built-in expansion port allows
cascading of up to 6 NWK954s to build a 24-port repeater
with no additional components and also allows stacking of
up to eight 24-port repeaters with the addition of simple
backplane driver/receiver components. The operating status
of the device is indicated on 14 outputs designed to directly
drive LEDs. This high level of integration combined with low
power consumption and low pin count offers an efficient and
low cost solution for Fast Ethernet unmanaged repeater design.
Compliance with Standards
The NWK954 is designed for compliance with the IEEE 802.3
Standard, Clause 24 (100BASE-X PCS and PMA), Clause 25
(100BASE-TX PMD) and Clause 27 (Repeater for 100Mb/s
Baseband Networks). Clause 25 references the FDDI twisted
pair PMD Standard, henceforth referred to as TP-PMD.
Compatibility With Other Devices
The NWK954 is designed to connect directly to 5 other
NWK954 devices using the expansion bus. The Expansion Port
is identical to that used on the NWK950 Repeater Controller.
The Expansion Port may be connected to a backplane through
external driver/receivers. The backplane specification is identical
to that used by the NWK950, so repeaters using the NWK950
may be stacked with repeaters using the NWK954.
