42.5 Devices

Various building blocks exist for developing KNX compatible devices. Dierent transceivers are

required

depending

on

the

transmission

medium.

For

TP1,

four

dierent

transceiver

solutions

allow

optimization

of

the

KNX

device

design

in

accordance

with

the

area

of

application.

A

transceiver

circuit

constructed

from

discrete

components

oers

low-cost

bus

access,

but

requires

high

certication

eort.

e

use

of

the

FZE

1065

transceiver

IC

with

transformer

coupling

and

bit

interface

allows

a

highly

resis-

tant

solution,

while

the

FZE

1066

transceiver

with

direct

bus

coupling

enables

a

resistant

and

miniatur-

ized

solution. ...
