ML6673 - Fast Ethernet/FDDI TP-PMD Transceiver

General Description

The ML6673 is a complete monolithic transceiver for 125 Mbaud MLT-3 encoded data transmission over Category 5 unshielded twisted pair and shielded twisted pair cables.

The ML6673 integrates the baseline restoration function defined in the TP-PMD standard.

Key Features

December 1998 ML6673 Fast Ethernet/FDDI TP-PMD Transceiver GENERAL DESCRIPTION The ML6673 is a complete monolithic transceiver for 125 Mbaud MLT-3 encoded data transmission over Category 5 unshielded twisted pair and shielded twisted pair cables. The ML6673 integrates the baseline restoration function defined in the TP-PMD standard. The adaptive equalizer in the ML6673 will accurately compensate for line losses exceeding the IEEE 802.3u limit of 100m of UTP. The ML6673 receive section consists of an equalizing filter with a feedback loop for controlling effective line compensation. The feedback loop contains a filter and detection block for determining the proper control signal.
