Functional Description
Introduction
The Intel
and Media Attachment Unit (MAU) functions, as defined in the IEEE 802.3 specification. It
functions as an integrated PLS/MAU for use with 10BASE-T twisted-pair networks.
The LXT905 interfaces a back-end controller to a twisted-pair (TP) cable. The controller interface
includes a transmit and receive clock and NRZ data channels, and mode control logic and
signaling. The twisted-pair interface comprises the following two circuits:
In addition to the two basic interfaces, the LXT905 contains an internal crystal oscillator, and four
LED drivers for visual status reporting.
The back-end controller side of the interface defines functions.
The LXT905 performs all required functions defined in the IEEE 802.3 10BASE-T MAU
specification as follows:
•
•
•

•
Twisted-Pair Input (TPI)
Twisted-Pair Output (TPO).
The LXT905 transmit function refers to data transmitted by the back-end to the twisted-pair
network.
The LXT905 receive function refers to data received by the back-end of the twisted-pair
network.
