The low cost basic FlexRay™ transceiver is part of the
electrical, physical layer in a FlexRay™ communication
network. The E910.54 provides an interface between
the twisted pair physical bus medium and a communication controller (CC). An SPI interface connects the
bus driver (BD) to a host controller (HOST) to provide
status information concerning failure detection on the
bus lines (e.g. short-circuits, ground loss) and overtemperature condition. An interrupt signal is generated
whenever the failure status changes.
Part of the FlexRay™ electrical, physical layer
Interface between the communication controller
and the transfer medium (twisted pair bus line)
Support of data rates up to 10 Mbit/s
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
Low EME due to balanced differential transmission
Applications
ÿ Transceiver in FlexRay™ nodes (ECUs)
ELMOS is member of the FlexRay consortium
