Function
■ B82789C0:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly.
■ B82789S0:
Suppression of asymmetrical (by L
) and symmetrical interference (by L
R
coupled in on lines. The high-frequency portions of the symmetrical data
signal are decreased so far that EMC problems can be significantly reduced.
Applications
■ Automotive applications, e.g. CAN and FlexRay bus
■ Industrial field bus systems
■ Line cards for telecom
