XMCAP2000: XMC Carrier Card for AcroPack® Modules

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.

Specifications

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.

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.
