10.0 FUNCTIONAL DESCRIPTION

MTD907 is an Ethernet Endec and 10BaseT transceiver with a built-in waveform shaper that performs the

Media Attachment Unit (MAU) and Physical Layer Signaling (PLS) functions as defined in the IEEE802.3

specification.

MTD907 can function as either a PLS-only device interfacing a supported controller to an AUI cable or as an

integrated PLS/MAU interfacing a supported controller to the TP cable. In the following functional descriptions,

aII functions are defined as seen from the controller side of the interface.

Controller Compatibility

MTD907 is configurable for interfacing with common industrial standard Ethernet controllers. The mode

selection pins, MD0 and MD1, provide the mode configuration capability as tabulated in Section 2.0. The timing

specification of different controller modes is specified in Section 8.0’s RXC timing. Applicable timing diagrams

for each of the supported controller modes are included in Section 9.0.
