TTX <strong>Optical</strong> <strong>Link</strong><br />
<strong>Optical</strong> Decoupling of FlexRay Networks<br />
TTX <strong>Optical</strong> <strong>Link</strong> enables the electrically reactive<br />
decoupling of FlexRay bus signals during the<br />
EMC test via an optical transmission line. On<br />
this point, FlexRay measurement systems<br />
outside of the EMC chamber can be simply<br />
connected to the test system.<br />
<strong>Optical</strong> Transmission of FlexRay signals<br />
TTX <strong>Optical</strong> <strong>Link</strong> is a compact device to decouple<br />
FlexRay bus signals via an optical transmission<br />
line. It enables the bi-directional optical<br />
transmission of FlexRay signals up to 30 meters<br />
(extension up to 100 meters possible on request)<br />
while ensuring minimum influence on the signals<br />
bit timing. Therefore, adaptation of the physical<br />
layer parameters is not needed.<br />
With its innovative shielded housing design and<br />
built-in accumulator it fulfills all the requirements to<br />
run EMC tests for FlexRay-based systems while<br />
enabling full access to the FlexRay bus using<br />
common analyzing tools.<br />
KEY FEATURES/BENEFITS<br />
<strong>Optical</strong> decoupling for FlexRay signals<br />
Minimal effect on FlexRay time-response<br />
Fulfilling the requirements of ISO 11452-2<br />
and CISPR 25<br />
Interference and emission-free<br />
Operation Area<br />
The TTX <strong>Optical</strong> <strong>Link</strong> is perfectly suitable as<br />
decoupling device for monitoring FlexRay systems<br />
in an EMC-sensible surrounding. Due to it’s<br />
bidirectional character it supports both sending and<br />
receiving data. TTX <strong>Optical</strong> <strong>Link</strong> features an<br />
accumulator for 24 hour continuous use and fulfills<br />
the requirements of the ISO 11452-2 and<br />
CISPR 25 standard.
