Part of the FlexRay™ electrical, physical layer

Active star coupler connects up to 4 branches

(FlexRay™ busses) to nodes or other active stars

Support of data rates up to 10 Mbit/s

Optional support of low power mode for an ECU

Remote wake up via bus line

The star coupler is part of the electrical, physical layer

in a FlexRay™ communication network. The E910.56

provides interfaces to connect up to four branches of

twisted pair physical bus lines to other bus drivers or

star couplers. It also interfaces with a communication

controller (CC) and a µC.Via SPI the bus driver (BD) pro-

vides status information concerning failure detection

on the bus lines (e.g. short circuit, ground loss) and

overtemperature condition to a host controller (HOST).

An interrupt signal is generated whenever the failure

status changes.

Enhanced diagnosis capability provided via SPI

with interrupt generation

Protection against overload damage by current

limitation and overtemperature detection

Bus driver outputs withstand - 27 V / + 40 V DC

voltage

The device supports normal and standby modes and

provides remote wake up capability via bus line. The

output (INH) can be used to control an external vol-

tage regulator.

Low EME due to balanced differential transmission

Star coupler and additionally usable as transceiver

in FlexRay™ nodes (ECUs)

ELMOS is member of the FlexRay consortium
