6747 Power requirements

Hi Ringo,

Have you seen page 58 of the datasheet? Is that you are asking for?

Most data sheets will have a max current requirement. I just want to know that I need X Ma for the 3.3V rail, YMa for the 1.2V Rails, Etc so I can design a power supply. Page 58 mentions the pins max drive capability, but what does the core use when active, or sleeping, etc? There should be a table that tells you that stuff. Otherwise I have to waaay overspec the power supply and hope it is enough.

I'm searching for that.

Have you seen the example of design on the C6747 EVM?

The schematics can be found at:

http://support.spectrumdigital.com/boards/evmomapl137/

I see that, but I have 3 DSPS, and FPGA, and other circuitry to power so I need totals.

The final power consumption data is not ready yet as this is a new product.

Till then, you can work with the preliminary estimates and the design guidelines/sizing data shown at:

Sorry, I sent the wrong link, this is the link for C6747:

Thanks, That gives me a good idea.
