High-Speed Bus

The motherboard connects the two daughterboards with two High-Speed Buses (HSB). The bus

interconnect can provide up to:

• 360 single-ended signals.

• 160 Low Voltage Differential Signalling (LVDS) signal pairs.

Note

• The HSB typically implements a multiplexed AXI bus.

• There is no connection from the HSB to devices on the motherboard. See the

documentation for your daughterboard.

PCIe Bus

The motherboard supports four PCI-Express (PCIe) slots, x4, x4, x8, and x16 connector sizes,

each with a lane width of four. A PCI-Express switch connects these slots to the daughterboards

over the PCIe bus that has eight lanes to each daughterboard. See Figure 2-1 on page 2-2 for

more information.

Note

The V2M-P1 motherboard supports a root complex either on the daughterboard in Site 1 or the

daughterboard in Site 2. By default the daughterboard in Site 1 is the root complex.

The V2M-P1 motherboard does not support an endpoint on either daughterboard.

See PCI-Express on page 2-15.
