9.4 Function Groups
Fig. 9-3 ES891.x Function Groups
9.4.1 Ethernet Switch
In addition to the Ethernet connection in the system connector of the stack (see
chapter
3.3 on page 24), the Ethernet switch of the module provides interfaces for
the connection of further modules:
- a HOST Ethernet interface (see chapter 12.1 on page 89)
- an FE Fast Ethernet interface (see chapter 12.2 on page 90)
- two GE FETK/Gigabit Ethernet interfaces (see chapter 12.4 on page 92)
9.4.2 Interfaces to the Vehicle Bus
The interfaces to the vehicle bus are available in different combinations:
- five CAN / CAN FD interfaces (see chapter 12.7 on page 102)
- one LIN interface (see chapter 12.8 on page 105)
- one FlexRay interface (see chapter 12.6 on page 100)
9.4.3 Other Function Groups
- Power supply (see chapter 3.4 on page 24)
- Function groups for power-saving functions ("Wake-Up", see chapter 11.3
on page 79)
