Part Number: DP83848I

Hi ,

AS per the DP83848 datasheet the typical power consumption is 270mW. (Page 17)

IDD 10BASE-T (Full Duplex) is mentioned as 92mA(Typical). Then power will be around 280 mW.

Please clarify.

Thanks,

Hi Divya,

Given most of the use-cases are for 100M bit, the typical power will be 81*3.3=267 mWatt and inline with <270 mWatt.

Again please note these are typical numbers at Nominal Voltage, Nominal Temperature.
