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.
