Hi,
Are there specific current draw specifications for all three rails in all modes. The data sheet appears to only show total power.
Thanks,
Mitch

I am interested in characterizing currents for following modes:
RGMII to Copper (1G) (100m cable, 50% utilization)
RGMII to 1000Base-X (50% utilization)
1000Base-TX to 1000Base-FX (100m cable, 50% utilization)
Hi Mitchell,
Attached is the current consumption for the modes you requested.
RGMII to Copper mode (100m cable, 50% utilization) | |||||||||
Speed | VDDIO = 1.8V/3.3V | VDD2P5 = 2.5V | VDD1P0 = 1.0V | VDD1P8 = 1.8V | |||||
