USB extension system

摘要: A USB extension system is disclosed which converts the standard signal into a low voltage differential and installed between hub or host device, drives interconnecting cable with true signal, i.e. balanced problems interference are greatly reduced. In accordance present invention, signals encoded form using of different magnitudes. one embodiment, “weak” magnitude used to encode “J” “K” states protocol, “strong” “EOP” (End Packet) state. further embodiment sync inserted data stream in order reconcile timing features protocol transmission delays can be expected over long lengths.
