LIN Transceiver, Dual
NCV7422
Description
The NCV7422 is a two channel physical layer device using the
Local Interconnect Network (LIN) protocol. It allows interfacing of
two independent LIN physical buses and the LIN protocol controllers.
The device is compliant to ISO 179874, LIN2.2a, LIN2.2, LIN2.1,
LIN 2.0 and SAEJ2602 standards.
The NCV7422 LIN device is a member of the invehicle
networking (IVN) transceiver family.
The LIN bus is designed to communicate lowrate data from control
devices such as door locks, mirrors, car seats and sunroofs at the
lowest possible cost. The bus is designed to eliminate as much wiring
as possible and is implemented using a single wire in each node. Each
node has a slave MCUstate machine that recognizes and translates
the instructions specific to that function.
The main attraction of the LIN bus is that all the functions are not
time critical and usually relate to passenger comfort.
