I did do a search first on this subject and did not come up with anything. The BBB the LAN8710 PHY is powered by the VDD_3V3B rail. The VDD_3V3B rail comes from a LDO sourced by SYS_5V and enabled by the PMCI VDD_3V3AUX. My questions are: 1) Why not power the PHY directly off of the PMIC VDD_3V3AUX? If OK use a analog switch like TPS27082 to EN power on PHY sequence? 2) Is the VDD_3V3B LDO for power-ON-sequence the PHY after the PMIC has already gone through power sequence? tks Mike
