ARRIA 10: The impedance between VCC and GND is only 2Ω

Folks, I just finished the soldering of Arria10 10AX115NF45 chip. After the soldering , I measured the impedance between VCC and GND and found that it was only 2 ohm, between VCCA_PLL and GND was only 20 ohm. Is this normal?At present, the PCB has not been powered on.

Thanks,

Hi Wu Kuang

We do not have specification for this. May I know your concern of this?

 

Thanks.

Dear Eng Wei

Thanks for your reply, I want to know if the impedance between VCC(0.9V) and GND is too low (2ohm)?  Is it damaged or  still nomal?  I have to make sure the chip is ok before power the board up.

Thanks and best regards,

Hi Kuang Wu

We don't have data on this so I am not able to confirm on this. What is the expected measurement? Are you trying to identify whether they are short circuit?

 

Thanks.
