GENERAL DESCRIPTION
The MX98905 is designed for easy implementation of
CSMA/CD local area networks, which include
Ethernet (10BASE5), Thin Ethernet (10BASE2), and
Twisted-pair Ethernet (10BASE-T). The Media Ac-
cess Control (MAC) and Encode-Decode (ENDEC)
are provided with an AUI interface. The 10BASE-T
transceiver functions according to the IEEE 802.3
standards, and the MX98905 10BASE-T transceiver
operations in compliance with the IEEE standard.
The functional block of the MX98905 consists of the
integration of the entire bus interface for PC-AT
(Industry Standard Architecture, ISA) bus-based sys-
tems, receiver, transmitter, collision, heartbeat,
loopback, jabber, and link integrity blocks. When
combined with equalization resistors, the transceiver
transmits or receives filters, and pulse transformers
provide physical interface from the ENDEC module of
the MX98905 and the twisted-pair medium.
When software and hardware are properly configured,
the MX98905 can be set to be compatible with either
the NE2000 or EtherCard PLUS16. All bus drivers
and control logic are integrated inside the chip to
reduce LAN card cost and area.
Manchester encoding and decoding is made possible
through the integrated ENDEC by means of a differ-
ential transceiver and phase lock loop decoder at 10
Mbit/sec. Collision detect translator and diagnostic
loopback capability are included in this process.
Interfacing directly with the transceiver module, the
ENDEC module also provides a fully IEEE-compliant
AUI (Attachment Unit Interface) to connect with other
media transceivers.
The Media Access Control function, provided by the
Ethernet Network Control (ENC) module, effects an
efficient packet transmission and reception control
through unique dual DMA channels and an internal
FIFO. To lessen board cost and area overheads, bus
arbitration and memory control logic are integrated.
Designed for easy interface with other transceivers by
means of the AUI interface, the MX98905 provides a
thorough single chip solution for 10BASE-T IEEE
802.3 network.
Constraints of CMOS processing require that
isolation, whether capacitive or inductive, be used at
the AUI differential signal interface for 10BASE5 and
10BASE2 applications.
