The part has a 2000 Volt static discharge voltage. The only high-speed part we have seen used for added ESD is a LittelFuse component, part number PGB0010603. This has been tested on some host controllers. It is referenced in the document "High Speed USB Platform Design Guidelines" which is on the usb.org web site. While some customers have used it on other Cypress high-speed parts, we have not tested it with the CY7C68000.
