Requirements for failsafe Automotive Ethernet Operation
For failsafe operation of the Automotive Ethernet communication channel, all
customer specific installations - including cables, connectors and board adap-
tations - have be compliant to:
• IEEE Std. 802.3bwTM-2015, “Amendment 1: Physical Layer Specifica-
tions and Management Parameters for 100 Mb/s Operation over a Sin-
gle Balanced Twisted Pair Cable (100BASE-T1)”, chapters 96.7 - 96.9
• Open Alliance, “BroadR-Reach® Definitions for Communication Channel,
Version 2.0”
NOTE
The BR_XETK-S1.0 Automotive Ethernet interface is not compatible with the
standard Ethernet interfaces of ETAS modules. An CBEB10x Media Converter
or an ES88x ECU and Bus Interface Module is required to connect the BR_X-
ETK-S1.0 to the PC (refer to chapter 4.3 on page 19).
NOTE
To achieve an appropriate channel performance all PCB board and cable seg-
ments have to be optimized with regard to line impedance matching, length
matching within the differential net routing or twisted pair cabling and on the
reduction of untwisted regions. Stub segments must be avoided for the
Point-to-Point cable connection in favor of inline connectors and shielding
measures shall be considered depending on the operation environment.
