This Würth Elektronik Webinar explains Ethernet connection types, benefits and also elaborated on suitable filter designs.
In the areas of process, building, and factory automation the demand for higher bandwidth communication is increasing. Single-pair Ethernet (SPE) can easily increase network bandwidth and reach in complex networks while meeting intrinsic safety requirements. In many cases, existing wires can be used.
The DP83TD510E from Texas Instruments helps designers implementing SPE on cables with varying characteristic impedances and lengths. 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 fulfill this requirement.
The Würth Elektronik Webinar presentation shows examples and detailed measurements for the filter design from connector to PHY chip to fulfill all requirements regarding signal integrity and safety according to IEEE802.3cg (10BASE-T1) and IEEE 802.3bw (100BASE-T1).
