Matrox Rapixo CXP - Electrical Specifications

60 Appendix B: Technical information
Electrical specifications
The following table describes electrical specifications for the Matrox Rapixo CXP.
The following table describes the specifications for the auxiliary I/O signals on
Matrox Rapixo CXP.
Operating voltage and current for Matrox Rapixo CXP
Matrox Rapixo CXP Typical: 3.3 V, 0.1 A mA (330 mW)
Typical 12.0 V, 1.4 A (17 W)
Max. PoCXP 18.5 - 24.0 V, 700 mA: 13 W (Current drawn from the internal auxiliary 12 V power connector.
Power is not dissipated by the board; it is only used by the video source).
Total dissipated by the board: 0.33 W + 17 W =17.33 W (typical)
Total dissipated by board and PoCXP video sources = 17.33 W + (4 * 17 W) = 85.33 W (typical)
