Only using 1 channel of the X557-AT2, what is the current consumption?

Hello,

I am using an x557-at2 ethernet controller, but only need to use one of the channels. I am trying to design the power rails for the device, so I am mainly looking at the maximum currents which in the case of this device , the 0.83V rail goes up to 8A. Since I am only using one channel would it be fair to design the rails to 50% of the maximums? If not, could you give me some guidance on what current values I should be using to design the power rails? Thank you.

p.s. I realize x557-at exists, however it is not easily purchaseable right now and we therefore need to use the dual channel one.

Hello @kh12,

 

Thank you for contacting Intel Embedded Community.

 

This forum is for Embedded products, but in my opinion, the AT uses exactly the half as the AT2, 4 A, and AT4 16 A, it seems that 4 A is the maximum current that may be assigned to each port, seems good to design for one port and also, disable one port from the NVM image.

 

Best regards,

Hello @kh12,

 

Well, in Ethernet forum they should try to help, if not there is our IPS service too.
