Abstract:
1. A universal serial bus hub comprising: a Universal Serial Bus (USB) Analog Front End (AFE) circuit module; a hub core; an isolator circuit module interposed between said USB AFE circuit module and said hub core, such that data communications between said hub core and said USB AFE circuit module pass through said isolator circuit module, said isolator circuit module serving to provide galvanic isolation between said hub core and USB AFE circuit module; a first isolation adapter circuit module interposed between said USB AFE circuit module and said isolator circuit module, such that data communications between said USB AFE circuit module and said isolator circuit module pass through said first isolation adapter circuit module, wherein said first isolation adapter circuit module comprises a first analog interface circuit module coupled to said isolator circuit module and a first parallel to serial converter module coupled to said first analog interface circuit module and said USB AFE circuit module; and a second isolation adapter circuit module interposed between said isolator circuit module and said hub core, such that data communications between said hub core and said isolator circuit module pass through said second isolation adapter circuit module, wherein said second isolation adapter circuit module comprises a second parallel to serial converter module coupled to said hub core and a second analog interface circuit module coupled to said second parallel to serial converter module and said isolator circuit module.
