Part#: FT3120-E4S40
Part Category: Telecom ICs

Manufacturer: Echelon Corporation

Description: Manchester Encoder/Decoder, PDSO32

The FT 3120 and FT 3150 Free Topology Smart Transceivers
integrate a Neuron® 3120 or Neuron 3150 network processor core,
respectively, with a free topology twisted pair transceiver to create a
low cost, smart transceiver on a chip. Combined with Echelon’s
high performance FT-X1 or FT-X2 Communication Transformer, the
FT 3120 and FT 3150 smart transceivers set new benchmarks for
performance, robustness, and low cost. Ideal for use in LONWORKS®
devices destined for building, industrial, transportation, home, and
utility automation applications, the FT 3120 and FT 3150 Free
Topology Smart Transceivers can be used in both new product
designs and as a means of cost reducing existing nodes.
The integral transceiver is fully compatible with the TP/FT-10
channel and can communicate with devices using Echelon’s
FTT-10A Free Topology Transceiver, and, when used with suitable
DC isolation capacitors, the LPT-11 Link Power Transceiver. The
free topology transceiver supports polarity insensitive cabling using
a star, bus, daisy-chain, loop, or combination topology (see Figure
1)—freeing the installer from the need to adhere to a strict set of
wiring rules. Free topology wiring reduces the time and expense of
node installation by allowing the wiring to be installed in the most
expeditious and cost-effective manner. It also simplifies network
expansion by eliminating restrictions on wire routing, splicing, and
node placement.
