PRODUCTION DATA
There must be no metal layer running beneath the transformer. Transformers can inject noise into metal beneath them, which can affect the performance of the system. Because the DP83822 is a current mode line driver design, the center tap pin on the device side of the transformer must be tied to the analog supply rail (AVD). De-coupling capacitors must be placed near the center tap pin of the transformer as shown in Figure 9-2.
