... USB2412 has been designed to illustrate such an implementation with its outer two layers. Many unpopulated (DNP) sites are incorporated to support optional EMI and ESD support components beyond the minimal BOM for proper function. Revision A1 of the EVB-USB2412 also has an added resistor (R23, 100 Kohms) pull down on NON_REM1 for configuration purposes. Revision 0.2 (02-02-10) ...

... Connector Description The EVB-USB2412 has a set of standard USB style connectors, one of type B for the upstream port and two of type A for downstream ports. Power is supplied via a 2.1 mm power jack. of the connectors. For more details on the pinout of these connectors, please see the EVB-USB2412 schematics on the CD-ROM included with your EVB-USB2412 ...
