Hi!

In the layout of the cyusb3014 chipset footprint seems that have a dissipator, is it necessary? 

Thanks in advance!

There is no heatsink for FX3 on the DVK board. How did you infer there is a heatsink from the footprint?


www.cypress.com/?docID=33570 is the hardware design guidelines. Use this and you should be fine.


Regards,
Anand

In the following image you can see the footprint, arround de chipset pins there are a shape in Place_Bound_Top layer

and various mechanical pins, I have assumed that it seem a dissipator. 

What's the use of this shapes and holes? May be for EMI or ESD purposes? I can skip this clearance?

Grateful!!!
