Pci-X-To-Pci-X Bridges; Pci Mezzanine Card Slots - SMART Embedded Computing MVME3100 Installation And Use Manual

The MVME3100 uses two of the four SATA channels. Channel 0 is routed to a SATA
connector mounted on the front panel for an external drive connection. Channel 1 is routed
to a planar SATA connector for an inside the chassis drive connection. Collocated with the
planar connector is a SATA power connector.
The MVME3100 provides two programmable LEDs to indicate SATA channel activity.

Related Documentation, for additional details and/or programming information

PCI-X-to-PCI-X Bridges

The MVME3100 uses two PLX PCI6520 PCI-X-to-PCI-X bridges to isolate the primary PCI
bus, bus A. These bridges isolate bus A from bus B with the PMC sites and from bus C with
the USB controller and PMCspan interface. The PCI6520 is a 64-bit, 133MHz, PCI-X r1.0b
compliant device. It operates asynchronously between 33MHz and 133MHz on either
primary or secondary port. Refer to the PCI6520CB Data Book listed in
Related Documentation, for additional details and/or programming information.

PCI Mezzanine Card Slots

The MVME3100 provides two PMC sites that support standard PMCs or PrPMCs. Both
PMC sites are located on PCI bus B and operate at the same speed and mode as
determined by the slowest PMC module. The board routing supports a maximum of
100MHz PCI-X operation on each site. Signaling voltage (Vio) for the two PMC sites is
dependent on keying pin installation options and can be configured for 5V or 3.3V. Both
sites must be configured for the same Vio voltage or the Vio voltage will be disabled.
Each PMC site has enough 3.3V and 5V power allocated to support a 25 watt (max) PMC
or PrPMC from either supply.
