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.
The ML6673 also contains data comparators with
precisely controlled slicing thresholds and an MLT-3 to
NRZI translator.
The ML6673 transmit section accepts ECL 100K
compatible NRZ inputs and converts them to differential
current mode MLT-3 signals. Transmit amplitude is
controlled by a single external resistor.
