2.7.8.
XMC Interface
For easy and flexible configuration a standard XMC connector, J20, is available. The board uses one x8 PCI Express 2.0
interface operating at 5.0 GT/s and compliant with the ANSI/VITA 42.0 and ANSI/VITA 42.3 specifications. x8 PCI
Express 3.0 operating at 8 GT/s is available on request.
2.7.9.
CompactPCI Interface
The CP6006(X)-SA supports a flexibly configurable, hot swap CompactPCI interface. In the system slot the PCI
/
PCI-X
interface is in the transparent mode, and in the peripheral slot the CompactPCI interface is isolated so that it cannot
communicate with the CompactPCI bus. This mode is known as "passive mode".
2.7.9.1.
Board Functionality when Installed in System Slot
In the system slot, the CompactPCI interface can be either a 64-bit
/
66 MHz PCI or PCI-X interface via a dedicated PCI
Express-to-PCI-X bridge from Pericom (PI7C9X130).
The CP6006(X)-SA supports up to seven peripheral slots with 33 MHz and up to 4 peripheral slots with 66 MHz
through a backplane.
The PCI Express-to-PCI-X bridge detects the PCI mode (PCI or PCI-X) and the bus speed (33 MHz or 66 MHz) via two
PCI control signals on J1: PCIXCAP (pin B16) and M66EN (pin D21). The following configurations are supported by the
CompactPCI interface.

To support 66 MHz PCI
/
PCI-X frequency, the CompactPCI signaling voltage (VI/O) must be
3.3 V.
The CP6006(X)-SA provides automatic voltage detection for the VI/O to switch the PCI
frequency to 33 MHz in an 5V environment.
2.7.9.2.
Board Functionality when Installed in Peripheral Slot (Passive Mode)
In a peripheral slot, the board receives power but does not communicate on the CompactPCI bus; all CompactPCI
signals are isolated. In this configuration, the communication is achieved via the two Gigabit Ethernet ports as defined
in the PICMG 2.16 specification.
2.7.9.3.
Packet Switching Backplane (PICMG 2.16)
The CP6006(X)-SA supports two Gigabit Ethernet ports on the J3 connector in accordance with the CompactPCI
Packet Switching Backplane Specification PICMG 2.16. The two ports are connected in the chassis via the CompactPCI
Packet Switching Backplane to the Fabric slots "A" and "B". The PICMG 2.16 feature can be used in the system slot and
in the peripheral slot as well.
