Single Pair Ethernet - Filter Design

For Single Pair Ethernet according to IEEE802.3, safety requirements according to IEC62368-1 are valid. These correspond to a test voltage of 1500V/60s. 50 V isolation capacitors which are commonly used for automotive Ethernet applications cannot fulfil this requirement. The presentation shows examples and detailed measurements for the filter design from connector to PHY chip to fulfil all requirements regarding signal integrity and safety according to IEEE802.3cg (10BASE-T1) and IEEE 802.3bw (100BASE-T1).
