VXS
The VITA 41 (or VXS) standard enhances the core VMEbus standard with the addition of a new high-speed interconnect capability to the existing VMEbus interface. Current VXS technology is based on serial fabrics using 2.5 and 3.125 GB/s signal rates, and the new P0 connector is designed to support fabrics up to 6 Gbit/s.
VXS defines two types of boards, payload boards and switch boards.
Payload boards are very similar to existing VMEbus boards. They have the traditional P1 and P2 connectors and support a standard VMEbus interface, but add a new higher-speed P0 connector with eight full-duplex serial links that provide up to 2.5 GB/s of throughput in each direction. Payload boards retain complete mechanical and electrical compatibility with legacy VME boards – any VMEbus board that uses the traditional P1 and P2 connectors can be installed in a VXS payload slot.
VXS switch boards replace the traditional P1 and P2 connectors with higher density connectors for high-speed serial interconnection. Switch boards do not support direct connection to the VMEbus, although payload boards will typically provide a fabric-to-VME bridge capability that allow a switch board to access VMEbus resources through one of the payload boards.
Quixilica products include a wide range of payload and switch boards that can be configured for optimum flexibility in building a high performance signal processing system.
