General Description
The TP112 is a single chip media converter for
100Base-TX to 100Base-FX. The TP112 support one
100Base-TX port over CAT5 twisted pair cable and one
ECL interface to connect with fiber module to apply in
100Base-TX/FX converter application. On the
100Base-TX side, The TP112 is directly connected to
external transformers
The chip performs data recovery, clock recovery,
adaptive equalization, auto negotiation, and baseline
wander correction function. The TP112 is compliant with
the IEEE 802.3u standard.
