Hello,

 

The QDR datasheet recommends that during power up sequence to apply Vdd before Vddq. Is it mandatory during the power up sequence to apply Vdd before Vddq?

 

thanks

Hi,

You have to apply VDD earlier or at the same time as VDDQ for proper operation of the device. It is a requirement that the Core should be powered first or at the same time as the I/Os but not later than the I/Os. 

Thanks,

Pradipta.
