Carrier cards from Abaco Systems reduce cost for I/O flexibility

XMC, 3U VPX carrier cards, released by Abaco Systems, eliminate need for costly, time-consuming custom I/O development, says the company.

The MMS8010 Micro Mezzanine System (MMS) rugged 3U VPX carrier card and MMS6245 XMC carrier card are designed to enable flexibility in configuring the range of mixed signal I/O, typically required by advanced embedded systems, says Abaco Systems. At the same time, they minimise chassis slot occupancy, thus minimising the size, weight and power (SWaP) of the deployed system, says the company.

Both the MMS8010 and the MMS6245 carrier cards can also eliminate the need to develop custom I/O solutions, reducing cost, risk and time to deployment.

Abaco’s patented MMS system can deliver a range of serial protocols, digital I/O, audio and analogue interfaces via a choice of electrical conversion modules (ECMs). Up to six ECMs can be mounted on the MMS8010 3U VPX carrier, while the MMS6245 XMC can host up to four ECMs.

A typically challenging application requirement such as a modern radar digital signal processing (DSP) sub-system, requiring fast analogue and field programmable gate array (FPGA) technology, may also require mixed I/O functions such as four serial channels, two analog measurement channels and 16 digital channels. Before the advent of the MMS8010 and MMS6245 carrier cards, says Abaco Systems, this would have required either several cards to be configured, using precious chassis slots. Alternatively, it would require a custom solution to be developed with the accompanying investment of time and money. 

The MMS8010 is a 3U VPX custom off the shelf (COTS) carrier card that enhance the characteristics of the deployed system, at a deliverable cost, says Abaco systems. The MMS6245 offers the same benefits in the XMC form factor and allows I/O to be brought very close to the central processing unit (CPU) when combined with a single board computer (SBC).

According to Mrinal Iyengar, vice president, Product Management at Abaco Systems: “The MMS8010 and MMS6245 deliver all the benefits of a custom-developed solution in terms of providing an exact match for the application’s requirements – and all the cost, time and availability benefits of a COTS solution.”

The MMS8010 is offered in both a VITA 48.1 air-cooled configuration as well as a VITA 48.2 conduction cooled configuration. These options allow customers to move from development to deployment with a common set of hardware. The MMS6245 is available as a convection cooled solution.

The MMS8010 is VITA 65 -compliant and maps the 96 user-configurable pins to VPX backplane signals.  The MMS6245 is VITA 42.3 -compliant and maps the 64 user-configurable pins to the front panel via a 68-pin SCSI style connector. Both are pre-loaded with a default FPGA image compiled in Quartus Prime from Altera, Intel, with Qsys providing the interconnection between the Avalon bus IP components within the FPGA. The FPGA is effectively the engine for the carrier, orchestrating processing and I/O functions for the installed ECMs, notes Abaco Systems.
