Description
The XTend3100 is a dual PMC carrier card designed to provide a low-cost and compact platform for PMC modules. The XTend3100, in conjunction with a standard off-the-shelf ATX power supply, provides a complete desktop or benchtop PCI/PCI-X PrPMC and XMC platform for development, evaluation, and testing, without the need for an expensive and bulky CompactPCI/VME PMC carrier card and chassis.
The XTend3100 features four integrated 40-mm fans arranged in a push-pull configuration to provide ample airflow for even the most power-hungry PrPMCs (up to 45 W each). The XTend3100 also provides onboard +5V, +3.3V, and -12V power supples, sourcing only +12V from the ATX power supply. This arrangement avoids the voltage drop and ampacity problems commonly associated with powering high-performance PrPMCs using ATX supplies.
Another common problem with PrPMC development is lack of early access to P14 rear I/O ports. This is especially troublesome with conduction-cooled PrPMCs, which by design do not have Ethernet or Serial access via front panel connectors. The XTend3100 solves this problem by providing a PIM (PMC I/O Module) site for each PrPMC. These sites, when used in conjunction with the appropriate PIM (i.e. XIt2020 or XIt2040) can provide the necessary I/O during the early development stage, when custom backplanes/wiring harnesses are often not available.
The XTend3100 also features JTAG test support through two Addressable Scan Port JTAG devices, which isolate each PMC onto its own JTAG chain to provide maximum JTAG test speed and isolation. A 7x2 header is provided for use with boundary scan test equipment.
