Noise Suppression in Onboard Ethernet 100Base-T1

Onboard Ethernet includes communication systems used in automobiles. A variety of interface standards can be used, depending on the application. Some examples of communication systems are CAN/LIN, FlexRay, MOST, and Ethernet. Onboard Ethernet standards include 100Base-T1 with one pair and 100Base-TX with two pairs. But unwanted noise can become an issue, so Murata researched ways to suppress noise in onboard Ethernet 100Base-T1 applications.
