This board interfaces two AcroPack mezzanine modules to a PCI Express bus on an air-cooled XMC carrier.

Two AcroPack module slots give you the freedom to mix a variety of I/O functions (A/D, D/A, digital in, digital out, serial I/O, etc.) on a single board. Or, combine modules of the same type for almost one hundred channels on a single card. Either way, the XMCAP2020/2021 saves your precious card slots and reduces your costs.

Select I/O modules from Acromag’s offering or use most third-party mPCIe compliant modules.

Designed for COTS applications these XMC carrier boards deliver high-reliability and high-performance at a low cost.

AcroPack carriers are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.

PCI Express Bus Compliance

This device meets or exceeds all written PCI Express specifications per revision 2.1.

Includes a PCIe Gen 2 switch to expand the single host

PCIe port to two ports, one to each device (AcroPack or mini-PCIe).

The host port consists of four PCIe lanes, each of the miniPCIe sites have one lane each.

Field I/O Connectors

Front I/O
XMCAP2020-LF: Two 68-pin 0.8mm Champ cable connection. Pin assignments are defined by the installed AcroPack or mini-PCIe module.

Rear I/O
XMCAP2021-LF: One AcroPack routed to rear P14 connector and one AcroPack routed to rear P16 connection.

XMCAP2022-LF: One AcroPack routed to P16 and the second to P14. Intended for ARCX-4000 applications only

Ease of Use

A unique carrier and site number can be set for each AcroPack site by a DIP switch or geographical addressing. This provides the capability to distinguish a particular AcroPack module from others when multiple instances of the same module are used in a system.

JTAG signal are provided for programming and debugging the FPGA on some AcroPack modules. The JTAG ports of the two AcroPack modules are daisy-chained.

Physical

Physical Configuration
PCIe x4 lane
Length: 5.866 inches (149 mm)
Height: 2.9134 inches (74 mm)
Conforms to VITA 42 air-cooled XMC specification.

Environmental

Operating temperature: -40 to +70°C
Storage temperature: -55 to +125°C.
Relative humidity: 5 to 95% non-condensing.
Power
+3.3 Volts (±5%): 140mA typical
VPWR: +5 Volts (± 5%): 200mA typical
VPWR: +12 Volts (± 8%): <100 mA typical

The XMCAP2020/2021 has four DC/DC converters to provide the power supply voltages to the AcroPack modules that are not present at the host interface. The +1.5 Volt supply is sourced from the VPWR host power. The +5 Volt and ±12 Volt supplies are sourced from +3.3 Volt host power.

  • Description

    Screw terminal panels simplify field signal wiring. A cable connector provides a clean interface to the I/O board or module.

    Many termination panels have a compact footprint and mount neatly on a DIN rail strip. Other panels are designed for mounting directly onto a standard 19-inch computer rack.

    All of Acromag’s I/O boards have a corresponding termination panel. This convenience saves you the time and hassle of finding a compatible panel or crafting your own.
