The nonprofit CiA (CAN in Automation) association has established the SIG (Special Interest Group) 48-V transceiver testing. The scope is the development of specifications related to CAN-based and LIN-based networks in 48-V supplied systems. This includes test plan specifications for 48-V physical media attachment (PMA) sublayer implementations.
The automotive industry is going to completely supply passenger cars with 48 V. The benefit: thinner power supply cables, reducing the wire harness weight. On the other hand, in-vehicle networks need to withstand higher voltage shorts. Loss of ground (GND) is also an issue. This means, PMA sublayer implementations such as PHYs, SBCs
