Blackfin 533 silicon 400MHz = 500MHz?

Hi all,

Does anybody happen to know if the 400 and 500 MHz types of the ADI 
BF533 chips share the same silicon (and are just selected)?

In other words: Do I have to expect any changes in EMI when using the 
500MHz part instead of the 400MHz part, both running at the same speed 
(approx. 250MHz)?

Thanks, Andre

To my experience, there is no difference between speed grades of ADI 
Blackfin. All grades perform the same as far as overclocking 
capabilities, power consumption and EMI.

Thanks a lot, sounds reasonable to me!
The 500MHz parts are cuurently available faster, thats why I asked...

Best regards,
