Technical Specifications
Technical Summary
The MSI MS-95A9 Revision 0A, dated 2004/05/04, is a 2U 5V PCI Riser Card designed for PCI 64/33 5V and PCI-X bus architectures. The board is identified by document number 0AMS-95A9 and PCB number MS-95A9-0A. It features three PCI slots operating on both 5V/33MHz and 3.3V/33MHz PCI buses, with a dedicated 5V/3.3V level shifter for voltage translation. The clock generation is handled by an ICW-W16 clock generator. The PCB is a 4-layer design with a 47 Core (1/1) structure, using H oz foil on layers L1 and L2, and 1 oz foil on layers L3 and L4. The prepreg thickness between L1-L2 and L2-L3 is 3.5 mil, with a controlled single-ended impedance of 50 ohms at 5 mil trace width.
