Hi All,  I am using T2080 processor.As per processor ethernet spec, EMI1 will support 2.5V/1.8V. EMI2 will support 1.2V. I am interfacing two marvell 88E1512 (1.8V) phy tranceiver (RGMII) to both of the EMI separately. Please let me know this voltage level mismatch will make any hamper to the ethernet interface. Thanks in advance.
