EXC-8000ccVPX Multi-Protocol Board

The EXC-8000ccVPX is part of the 8000 family of multiprotocol carrier boards. This conduction cooled VPX interface board has a PCI Express host interface and can support up to four independent removable modules and 10 on-board Discrete channels. Each removable module can be any of the 8000 family modules.

The EXC-8000ccVPX supports Direct Memory Access (DMA), which enables the board to access system memory for reading and writing independently of the computer’s CPU. This results in faster data transfer to and from the board, with much less CPU overhead than when not using DMA.

The EXC-8000ccVPX is supplied with C drivers, including source code.

The EXC-8000ccVPX is a VPX 3U Daughter card designed and conforms to the ANSI-VITA 65.0-2019 Open VPX System Standard. This specification allows for a wide variety of communication protocols including Ethernet, USB, PCI Express, serial and many more. The PCI Express protocol is the Host interface used in our Excalibur card EXC-8000ccVPX.

The specification defines a broad methodology of how these protocols are mapped from the VPX daughter cards to the VPX Back plane. This mapping is defined as Slot Profiles. They describe the type of signal to be routed and how each pin or pair of pins are allocated. Each slot profile is divided into 4 different planes - the Utility, Control, Data and Expansion planes.

 Utility Plane: This section of the slot profile, in general, provides all the required power pins along with discrete signals and system management signals.

 Control, Data and Expansion planes: These sections of the slot profile are where the dedicated differential protocol signals as well as the customized User Defined I\O data signals are routed.

The communication protocol signals are grouped together into the specific differential pairs which are defined as “Pipes”. Each slot profile defines and specifies the precise position and allocation of these pipes. The EXC-8000ccVPX is Compatible with VITA 65 Peripheral Slot profile:

(x1 PCIe) – Thin Pipe (1 Tx & 1 Rx)

as shown below

Where the x1 PCIe Host Interface signals are routed to data plane. All of the User IO signals have been routed to the differential connector P2. The differential P1 connector has no User IO signals routed to it in order to enable the EXC-8000ccVPX to be compatible with the following additional VITA 65 profiles:-

SLT3-PER-1F-14.3.2 (x4 PCIe) – (4 Tx & 4 Rx)

SLT3-PER-2F-14.3.1 (x8 PCIe) – (8 Tx & 4 Rx)

SLT3-PER-1Q-14.3.4 (x16 PCIe) – (16 Tx & 16 Rx)

These profiles have their PCIe Host Interface signals routed to the P1 differential connector as shown below. Thus, the EXC-8000ccVPX can be inserted into the VPX Backplane that supports any of the above slot profiles and will communicate seamlessly via it’s 1x PCIe pipe interface.

In the VITA 65 Specification recommends that eco-systems gradually migrate to using only the following power inputs from the backplane: 12 VDC, 3.3V_AUX, and VBAT. It is for this reason the EXC-8000ccVPX was designed by default to run solely the 12VDC supply from the back plane. However to provide backward compatibility the option for the following legacy power supplies was implemented as an optional feature : +5V, +3.3V.
