Quote - Since I'm not using the internal LDO, can I drop connecting it?
Quote - Do I still need capacitors close to the power pins on the PHY chip? (As in Figure 7 from the app notes)
Quote - What is the recommended way to wire up the DVDDH 3.3V?
Quote from: stride on November 19, 2016, 05:40:42 amI'm designing using these assumptions: - The capacitors can be fed from the power supply through any number of vias, the point is to have a steady trickle of power. - The capacitors is the actual elements feeding the IC, they should have an as short path as possible between Vcc and GND on the IC. - The big capacitor is the one feeding the smaller ones.Are my assumptions correct?
