Multi-Function I/O Module plugs into FPGA computing boards.
November 30, 2011 -
Designed to plug directly into PMC and XMC reconfigurable FPGA cards equipped with AXM mezzanine connector, Model AXM-A75 provides A/D conversion, D/A outputs, and discrete level monitoring/control functions. Module has 16 differential analog input channels, each with 16-bit 250 kHz A/D converter. Two quad DAC devices drive 8 analog output channels with range of ±10 V. Each channel has high-speed 16-bit D/A converter, which allows updating of individual channels or all outputs simultaneously.

New I/O Extension Module Adds Analog and Digital I/O Processing Capabilities to FPGA Computing Boards
Acromag's new AXM-A75 multi-function I/O module plugs into their PMC and XMC FPGA cards to provide front-end A/D conversion, D/A outputs, and discrete level monitoring/control functions.
Wixom, MI: The new AXM-75 is a multi-function I/O extension module that adds A/D, D/A, and digital I/O signal processing functions to a FPGA processor board. Acromag's extension I/O modules plug directly onto their PMC and XMC reconfigurable FPGA cards equipped with an AXM mezzanine connector. Using the AXM-A75, engineers can interface a number of high-level analog voltage signals to and from the FPGA. TTL-level digital I/O channels can monitor and control discrete devices. A 68-pin VHDCI receptacle provides easy field I/O connections. The operating range is -40 to 85°C. Typical uses include hardware simulation, in-circuit diagnostics, machine control, signal intelligence, and image processing. List price is $1700.
"The AXM-A75 multi-function I/O module simplifies the interface between an FPGA and sensors or controllers" explained Joseph Primeau, Acromag's sales and marketing director. AXM extension modules like the AXM-A75 provide a convenient method to interface real-world signals to and from the FPGA for high-speed measurement and control operations.
There are sixteen differential analog input channels on the AXM-A75. Each input has its own high-speed 16-bit 250kHz A/D converter offering the ability to simultaneously sample all channels. A low-pass filter removes unwanted EMI. The input range is ±10 volts with programmable gain of 1x, 2x, 4x, or 8x. Serial FLASH memory stores the factory calibration constants.
Two quad DAC devices drive eight analog output channels with a range of ±10V. Each channel has its own high-speed 16-bit D/A converter which allows updating of individual channels or all outputs simultaneously. The D/A settling time is 10µS.
Sixteen bi-directional digital I/O channels provide the ability to read or write 5V logic levels on TTL devices. Each I/O channel is individually configurable as an input or output for great flexibility to match your requirements. The open drain outputs are pulled high via a pull-up resistor.
