DP83825I: POWER SEQUENCING AND CURRENT

SATHYA SHREE S
Intellectual 650 points
Part Number: DP83825I

Hi,

We are using DP83825IRMQR in our design for RMII interface. Do we need any power sequencing for the voltage rails VDDIO and VDDA3V3 for proper operation. 

And also we are using TLV320AIC3110IRHBR for I2S interface. In datasheet it is mentioned as first speaker supplies should be powered on and then digital supply and analog supply, do we need power sequencing for these rails also. Can you please provide the maximum current values for each of the rails (AVDD, DVDD, HPVDD, SPLVDD, SPRVDD, IOVDD) it is not mentioned in datasheet, as we are going to use 1W speaker in SPLVDD(5V), SPRVDD(5V), We need to know about the current values.

Thanks
