4194B–AUTO–12/04
Figure 7 shows a normal VAN bus frame. It is initiated with a Start of Frame (SOF)
sequence shown in Figure 9. The SOF can only be transmitted by an autonomous mod-
ule. During the preamble, the TSS461E will synchronize its bit rate clock to the data
received.
Figure 9.
Framing Sequences
When the complete SOF sequence has been transmitted or received, the circuit will
start the transmission or reception of the identifier field.
All data on the VAN bus, including the identifier and Frame Check Sum (FCS), are
transmitted using enhanced Manchester code.
In enhanced Manchester code, three NRZ bits are transmitted first followed by one
Manchester bit, then three more NRZ bits followed by one Manchester bit and so on.
Since the high state is recessive and the low state is dominant, the bus arbitration can
be done. If a module wants access to the bus, it must first listen to the bus during one
full End of Frame (EOF) and one full Inter Frame Spacing (IFS) period, to determine
whether the bus is free or not (i.e.,no dominant states received).
