    ESD performance with CY7c65642

      Hi,

         

      I have a carrier board with touchscreen and SMARC connector. The touchscreen is connected via USB hub (USB2.0 full speed)

      When I connect a SMARC module with SMSC2532 USB hub controller from Microchip and zap the touchscreen with ESD 8kV air discharge, I see no problem with the touch.

         

      When I connect a SMARC module with CY7C65642 USB hub controller and perform the same ESD test, the touch screen stops working.

         

       

         

      I could find the ESD performance of the microchip hub which conforms to JEDEC class 3A but I cannot find any information for the CY7C65642 hub controller.

         

      Please guide.
