DP83848T: Reference for timing measurement

Part Number: DP83848T

Hi Team,

Just a minor clarification on what to reference upon performing timing measurements with the DP83848T. We are aware that the device has a power-on reset (POR) feature but we are in doubt if the PHY is already initialized at this state.

After the POR has been triggered, the hardware reset is still present for a certain time, so the power-up will be over. At this point must we use the reset timing diagram (Figure 5-2) for the measurement, not the power-up timing diagram?

Thanks in advance!

Kind Regards,
