Trenton Technology BPG6741 2U Butterfly Graphics Class PCI Express Backplane

Trenton Technology's BPG6741 is a graphics-class backplane with four PCI Express™ option card slots. The butterfly form factor of the BPG6741 is designed for use in a 2U chassis.

Features:

• Butterfly form factor supports PCI-Express™ option cards
• Supports 2U Chassis designs
• One SHB Express™ (PICMG® 1.3) System Host Board Slot
• One x16 PCI Express Slot (mechanical)
• Three x8 PCI Express Slots (mechanical)
• Audio port for speaker and microphone interface
• Optional two USB 2.0 backplane I/O connections
• Optional 10/100/1000Base-T backplane Ethernet port

System Host Board Slot

The Trenton Technology BPG6741 backplane accepts an SHB Express™ (PICMG® 1.3) compliant (graphics class) processor such as a Trenton T4L, TML or MCG-series system host board.

PCI Express Serial Slots

PCIe1 and PCIe3 option card slots are located on side B of the butterfly backplane. Side B is opposite the SHB and the side B slots are driven by x1 PCI express links. The Trenton SHBs support the auto-negotiation and link training features of PCI Express that enables PCIe1 and PCIe3 option cardslots to support x8, x4 and x1 PCI Express cards. PCIe4 is a x16 mechanical slot located on side A of the backplane or the SHB side of the backplane. PCIe4 is driven with a x16 PCI Express link from a graphics-class SHB and is capable of supporting high-end PCI Express video and graphic cards.

Mechanical interferences may exist between the SHB's cooling solution and certain types of option card heat sinks used on a x16 PCI Express option card installed in backplane slot PCIe4. To ensure proper mechanical clearances regardless of option card heat sink type, Trenton recommends using either half-length or quarter-length x16 PCI Express option cards in backplane slot PCIe4. Please contact Sarsen Technology to ensure the mechanical compatibility of the BPG6471 in your application.

USB Audio Controller

The audio controller on the BPG6741 backplane eliminates the need to dedicate an option card slot to a sound card. The USB audio controller supports a variety of speaker, headset and microphone configurations. The high-performance stereo audio ADC/DAC, general purpose I/O connections and codec functionality are key features of the BPG6741’s audio controller.

The USB4 port from the Trenton MCG-series SHB provides the input for the USB audio controller and the USB4 input becomes Audio0 on the BPG6741 backplane. If a Trenton T4L or TML SHB is used, then the SHBs must be factory-equipped with the optional USB routing to the backplane. Likewise non-Trenton SHBs must provide the optional USB I/O backplane routing defined in the PICMG 1.3 specification in order to enable the audio functionality of the Trenton BPG6741 backplane.

Optional USB 2.0 Interfaces

Trenton's BPG6741 provides one USB 2.0 header capable of supporting two general purpose USB 2.0 backplane interface ports.

Optional Ethernet Interface

Trenton's BPG6741 backplane supports the optional Ethernet routing feature of the SHB Express (PICMG 1.3) specification. One 10/100/1000Base-T Ethernet RJ-45 connector is available for use on the Ethernet version of the backplane. The Ethernet port is located on Side B of the backplane. This required connector location may necessitate a mechanical modification to the chassis in order to facilitate proper backplane mounting within the enclosure.

Power Indicators

Surface-mount LEDs provide a convenient visual check for +5V, -5V, +5V AUX, +12V, -12V and +3.3V power connection and status. CAUTION: Never install or remove the SHB or any option card from the BPG6741 backplane if the +5V AUX LED is GREEN. If the system appears to be off and the +5V AUX LED is GREEN, you need to remove or turn-off the incoming power to the system power supply.

Auxiliary Power Connections

The +12V power connectors on the BPG6741 route auxiliary power to the SHB's edge connectors. This new capability of PICMG 1.3 compliant SHBs and backplanes eliminates the need for auxiliary power connections on the system host board.
