Re: Virtex-4 inrush power-on current

Austin,

Just curious: why even spec "Iccintmin is 244 mA typically" if Xilinx really wants their users to design for 1.65A on power-up/configuration?

I haven't read the data sheet on this part but the OP makes it sound like the data sheet suggests a lower power-up requirement if the design is within the nominal limits on voltage, temperature, etc...

KJ,

I am trying to politely say, he is on his on, he has exceeded the spec.

I am also saying that there are those who might test their systems in a burn-in oven, and reject the units that won't power on when hot.

If he has 10 units he has to ship next week, this might be a perfectly good temporary solution, until he re-designs his power supply.
