PCI/PCI-X Interfaces and Devices
The MVME3100 provides three separate PCI/PCI-X bus segments. Bus segment A operates in
66 MHz PCI or PCI-X mode and is connected to the MPC8540, the TSi148 VME controller, the
serial ATA (sATA) controller, and two PCI-X-to-PCI-X bridges. Bus segment B is bridged
between bus A and the two PMC sites and operates in 33/66 MHz PCI or 66/100 MHz PCI-X
mode depending on the slowest speed PMC installed. Bus segment C is bridged between bus
A, the USB controller, and the PMCspan connector. Bus C operates at 33 MHz PCI mode.

MPC8540 PCI-X Interface
The MPC8540 PCI-X controller operates in PCI or PCI-X, host bridge mode depending on the
state of the Bus A mode switch. The mode cannot be changed by software. Refer to the
MPC8540 Reference Manual listed in

details and/or programming information.
TSi148 VME Controller
The VMEbus interface for the MVME3100 is provided by the TSi148 ASIC. The TSi148 provides
the required VME, VME extensions, and 2eSST functions. Transceivers are used to buffer the
VME signals between the TSi148 and the VME backplane. Refer to the TSi148 User’s Manual
listed in

Serial ATA Host Controller
The sATA host controller uses the Intel GD31244 PCI-X to sATA controller. This device provides
four sATA channels at 1.5Gb/s and is compliant with the Serial ATA: High speed serialized AT
Attachment Specification, Revision 1.0e. It also supports the native command queuing feature
of sATA II.

Attachment Specification, Revision 1.0e. It also supports the native command queuing feature
of sATA II.
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. Colocated with the planar
connector is a sATA power connector. At power-up, the controller is configured to operate in
either legacy (Native PCI IDE) mode or Direct Port Access (DPA) mode, controlled by the sATA
mode switch. The mode cannot be changed by software.

The MVME3100 provides two LEDs to indicate sATA channel activity. The function of the LEDs
depends on the operating mode of the 31244 (legacy or DPA mode).
