MB86961A
UNIVERSAL INTERFACE FOR 10BASE -T

GENERAL DESCRIPTION
The MB86961A Universal Interface for 10BASE-T
(Twisted-Pair) Ethernet is fully compliant with the IEEE
802.3 specifications for AUI (Attachment Unit Interface)
and 10BASE-T (Twisted-Pair) interfaces and provides the
electrical interface between an Ethernet controller and the
DB15 (AUI) and RJ45 (10BASE-T) connections to an
Ethernet local area network. Functions provided by the
MB86961A include Manchester encoding and decoding
of the serial data stream, level conversion, collision detec-
tion, signal quality error (SQE) and link integrity testing,
jabber control, loopback, and automatic correction of
polarity reversal on the twisted-pair input.
Pulse shaping and filtering functions are performed by
the MB86961A to eliminate the need for external filtering
components and thus reduce overall system cost. The
device also provides outputs for receive, transmit, colli-
sion and link test LEDs and provides compatibility with
both shielded and unshielded twisted pair cables. The
receive threshold can be reduced to allow an extended
range between nodes in low noise environments. Its wide
range of features and its ability to interface to virtually all
popular controllers make the MB86961A the ideal device
for twisted pair Ethernet applications.
The MB86961A is part of a complete family of Ethernet
devices available from Fujitsu. It is fabricated in a low-
power CMOS technology and is supplied in a 44-pin
PLCC and 48-pin PQFP packages.
