To transmit information, Serial Back-Plane technology uses a low voltage differential signaling transmission method for sending information.
It could therefore take the place of the most common use of Ethernet, if it used equivalent signaling technologies ( such as Low voltage differential signaling ).
:From our PCI Express article : " At the electrical level, each lane utilizes two unidirectional low voltage differential signaling ( LVDS ) pairs at 2.5 Gbit / s.
Spacewire is very similar to DS-DE-02, except it uses a microminiature 9-pin " D " connector ( lower-weight ), and low voltage differential signaling.
One is to reduce the operating voltage of the circuit, as in a dual-voltage CPU, or to reduce the voltage change involved in a state change ( making a state change only, changing node voltage by a fraction of the supply voltage low voltage differential signaling, for example ).
