Thread Summary

                The user asked about the differences in the isolation transformer connections between the EVAL-ADIN2111EBZ and EVAL-ADIN2111D1Z evaluation boards. The EVAL-ADIN2111D1Z uses a larger transformer without a center tap to support power forwarding with smaller inductors (2x47uH), while the EVAL-ADIN2111EBZ uses a center-tapped transformer with common-mode termination components. No special requirements exist for the bypass relay, but stray capacitance should be kept very low (single-digit pF).

comparing the 2 schema of the EVAL-ADIN2111EBZ and EVAL-ADIN2111D1Z


A. why is there two different connections systeme and different parts at the isolation transformer parts between Connectors and PHY?


1. T1/T2 with 220uH and without middle connection and Functional ground (FS Earth) , 
or 
2. T1/T2 with Würth 74930000 with middle connection and Functional Ground with "C" to (Earth)


is this depending von using PoDL or not, or only related to the EMC requirements?




B. is there any special requirments for the BYPASS RELAY ?
