7.0 Validation Results
+ {5 R1 o- b/ B5 tTo validate the performance of the transformerless implementation, a DP83848 device was configured as represented schematically in Figure 5 using both 0.1 uF and 33 nF capacitors. Standard IEEE compliance testing as well as bit error rate testing was performed. Bit error testing was performed with a traditional link partner, which utilized magnetics, and with a transformerless link partner.
