PBP-20Q3 2 PICMG/3 PCI Quad System Passive Backplane He PBP-20Q3 backplane is fully PICMG Rev 2.1 compliant. It is a member of PBP’s PCI product family and is intended to support all PICMG compliant boards on the market. T The board’s main features include: 4 x Dual slot PCI/ISA for the CPU board for each single system Connector 4 x Three 5V 32bit PCI slots for full-size boards on the Primary bus. These slots are Master/Slave configurable by using Bus Mastering Scheme for each single system One AT standard power connector and one flush-mount AT standard power connector: 12 pins, 5A max. per pin for +5V, -5V, +12V, -12V voltages, Ground, and Power Good signal. One ATX standard power connector: 20 pins, 5A max. per pin for +5V, -5V, +12V, -12V , +3.3Vvoltages, Ground, and Power Good signal. One ATX control connector to distribute signals coming from the CPU boards onto connector for soft on/off an ATX power supply. Pairs of header for local connection of a keyboard and fan power for each single system Power LED The Printed Circuit Board’s (PCB) overall dimensions are 265.2mm x 415.4mm PCB (104.41”x163.54”), and total thickness is 1.6mm. Twenty-six mounting holes are provided and are located to conform to the baby AT form factor. Mounting holes are connected to Signal Ground internally. Operating temperature : 0℃ ~ 55℃ Storage temperature : -20℃ ~ 75℃ PCI- conforms to PICMG rev. 2.1 specification Standard ISA- conforms to IEEE P996 specification. 1.
