TP-MAU
Ethernet Twisted Pair Media Attachment Unit

(also called a transceiver)

The twisted-pair Media Atachment Unit (TP-MAU) is designed to allow Ethernet connections to use the existing twisted-pair wiring through an Ethernet Attachment Unit Interface (AUI). The TP-MAU provides the electrical interface between the AUI and the twisted-pair wire.

FEATURES:

• It meets or exceeds IEEE 802.3 standard for AUI and 10 Base T interface.
• It is designed to meet FCC Part 15 subpart J class A.
• Power supplied through AUI connector.
• CMOS technology.
• Double sided surface mount assembly, compact size.

FUNCTIONS:

• level-shifted data pass-through from one transmission media to another,
• collision detection,
• Signal Quality Error (SQE) testing, with disable switch,
• Link integrity testing with disable switch,
• automatic correction of polarity reversal on the twisted pair input with disable switch,
• LEDs for transmit, receive, jabber, collision, reversed polarity detect and link functions.
