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.
