    FX3 DVK DEVICE BOARD: REV - 3.0 Schematic Error or ??

    frank.walker

      I am currently implementing the FX3 into a project; I have the board and I have the schematics.

         

      My problem is that on page 9 of the schematics there seems to be an error, I didn't catch it until just now:

         

      On the USB3.0 MICRO -TYPE B connector:

         
            
      • MICRO_SSTX- (connector pin) is connected to SS_TX_M (signal)
      •     
      • MICRO_SSTX+ (connector pin) is connected to SS_TX_P (signal)
      •    
         

      the above part makes 100% sense to me.....

         

      but the following does not make any sense to me whatsoever

         
            
      • MICRO_SSRX- (connector pin) is connected to SS_RX_P (signal)
      •     
      • MICRO_SSRX+ (connector pin) is connected to SS_RX_M (signal)
      •    
         

      Am I missing something? I admittedly did not catch it initially, my experience tells me that

         
            
      • MICRO_SSRX- (connector pin) should be connected to SS_RX_M (signal)
      •     
      • MICRO_SSRX+ (connector pin) should be connected to SS_RX_P (signal)
      •    
         

      Is this schematic really representative of the system I have?

         

      Any and all input would be greatly appreciated as I am already to the layout stage and hope to have a functional board the first time around.

         

      Thanks!
