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.

Features
• Compatible with or exceeds IEEE 802.3 standards for AUI and 10BASE-T interfaces
• Internal pre-distortion generator for TP driver
• Smart squelch circuitry on all received data
• Selectable heartbeat function
• Selectable line-integrity test with LED indication
• LED indicator for transmit, receive, jabber, and collision
• Advanced analog CMOS process using single 5V supply
• Lower TP threshold option for long length application
• Selectable auto-polarity detection and correction function with LED indication
• Automatic AUI/RJ45 selection
• Power-down mode
• Full ESD protection
