Twisted-Pair Medium Attachment Unit

General Description

The DM9095 twisted-pair Media Attachment Unit

(TPMAU) is designed to allow Ethernet connections

to use existing Twisted-pair wiring plants through an

Ethernet Attachment Unit Interface (AUI). The

DM9095 provides the electrical interface between

the AUI and the twisted-pair wire.

generation, receiving squelch function, selectable

signal-quality-error (SQE) test generation, a link-

integrity strapping option, and automatic correction

of polarity reversal on the twisted pair input. The

DM9095 also includes LED drivers for transmit,

receive, jabber, collision, reversed polarity detect

and link status.

The DM9095’s functions include level-shifted data

pass-through from one transmission media to

another, collision detection, transmitting pre-

distortion

The DM9095 is an advanced CMOS device

available in 28-pin PLCC packages.
