(1) HDMI I2C is voltage boosted using VIN_5V0 power rail. Due to that VIN_5V0 = 5V is
recommended since HDMI EDID requires 5V voltage levels.
(2) AR8035 Gigabit Ethernet PHY consumes 150mA out of those in a 100meter cable
configuration.
This is reduced to 150mA when the AR8035 is not active.
This is reduced to 150mA when the AR8035 is not active.
(3) Assumes ultra-high speed: 1.8v, 100MHz clock rate and double data rate on data; 4
bit data on SD2 and 8 bit data on SD3.
(4) Assumes VIN_5V0 = 5v. When supplying less than 5V, the maximum current
increases accordingly; it is recommended to add additional margins on current limit.
