ADE7880 timing delay calculation approach

Question asked by Dinesh@Jadhav on May 4, 2017

We want to evaluate ADE7880 for our current project which is inverter application.

 

For which I want to estimate the total time delay from ADE7880 input to micro core for different data measurement condition .

 

As per ADE7880 datasheet,

 

Case 1 : HSDC port can be used in conjunction with I2C to provide access to ADC output & real time power information.

So for this raw data measurement, what will be total time delay from ADE7880 input to micro core. (ADC  timing + Processing timing  if any + Communication Bus timing with Host processor)

 

Case 2 : ADE7880 does all energy measurements with DSP core, in this case what will be total time delay to pass measuring info from ADE7880 input to micro core including metering chip DSP core function.(ADC timing + Settling time+ Processing time + Communication Bus timing)

 

Kindly confirm Case 1 & Case  2 approach for total time delay from ADE7880 input to micro core.

 

Thanks in Advance,

Dinesh Jadhav
