FlexRay transceiver

[3]

According to ISO7637, test pulse 3a, class C; verified by an external test house.

According to ISO7637, test pulse 3b, class C; verified by an external test house.

[5]

In accordance with IEC 60747-1. An alternative definition of virtual junction temperature Tvj is: Tvj = Tamb + P × Rth(j-a), where Rth(j-a) is a

fixed value to be used for the calculation of Tvj. The rating for Tvj limits the allowable combinations of power dissipation (P) and ambient

temperature (Tamb).
