Hello,
I'm designing a product using the ADIN3310 together with ADIN1300 for two gigabit Base-T ports and one gigabit host port.
In the datasheet under the section Power consumption and thermal considerations it says " When operating at 1 Gbps on all six ports, use VDDIO_B at 1.8 V or 2.5 V. Operating at VDDIO_B = 3.3 V when all ports are at a 1 Gbps speed is not supported".
Does this "Operating at VDDIO_B = 3.3 V when all ports are at a 1 Gbps speed is not supported" also apply to the three port version of the chip or can i use 3.3V for VDIO_B when both VDDIO_B ports and the VDDIO_A port are running 1Gbps RGMII?
Best Regards
