Hi all, I'm going to try to add a USB 2.0 hub to the USB host on the verdex 60 pins. The most simple chip I found is the CYC65630, is this one a good idea? Datasheet: http://download.cypress.com/publishedcontent/publish/design_resources/ datasheets/contents/cy7c65630_8.pdf Regards, Albert |

No, I mean that the PXA270 has an internal transceiver that only requires an external charge pump.
