      Hi,

         

       

         

      Greetings of the Day!!!

         

       

         

      I am Dinesh Katkar, I would like to share my product block diagram,where I have selected Cypress chip CY7C6563156LTXI for USB hub.I would like to request you to provide the support for the same.

         

      I have selected USB upstream port as 10118192-0001LF Micro-USB connector and USB downstream 4 ports as below..

         

      1. 2 ports of hub for Dual USB connector-61400826021

         

      2.one port of hub for USB to ethernet controller chip-(LAN9500IABZJ) 

         

      3.one port of hub for thermocouple reading through USB to SPI converter...

         

      I am bit confused with USB upstream port Micro-USB connector ? Can we use MicroUSB connector to connect this with RPi model B and will do controlling through Raspberry board.

         

      Also I found reference design for USB2.0 hub ,where I found 2 VBUS power switches MIC2026-2YM from micrel.Is it necessary?

         

       Looking forward for your positive response regarding support for Micro-USB connector selection as USB upstream port and 2 VBUS power switch requirements and suggest me if any modifications is required in my end product...

         

      kindly see the attached block diagram for the reference....

         

      Thanks and Warm Regards,
