EVAL-ADRV9009 Overheating

Hi,

I tried to evaluate EVAL-ADR9009 on ZCU102 Rev1.1 board. I connected to device and tried to evaluate it. But after a few minutes the temperature of the Eval-ADRV9009 reaches 85-90 celciuc degrees(Even if no complicated process is done). Is it normal? If not, why is the problem caused?

Thanks in advance
