Acromag introduces a new range of multifunction 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.
The new AXM-A75 multifunction I/O extension modules add A/D, D/A, and digital I/O signal processing functions to FPGA processor boards. The extension I/O modules plug directly onto their PMC and XMC reconfigurable FPGA cards equipped with an AXM mezzanine connector.
The AXM-A75 I/O modules typically find application in hardware simulation, in-circuit diagnostics, machine control, signal intelligence and image processing.
The AXM-A75 I/O extension modules allow engineers to interface a number of high-level analogue voltage signals to and from the FPGA. While TTL-level digital I/O channels can monitor and control discrete devices, a 68-pin VHDCI receptacle provides easy field I/O connections.
Key features of AXM-A75 multifunction I/O extension modules:
- Simplifies the interface between an FPGA and sensors or controllers
- Provides a convenient method to interface real-world signals to and from the FPGA for high-speed measurement and control
- 16 differential analogue input channels with each input having its own high-speed 16-bit 250kHz A/D converter
- Low-pass filter removes unwanted EMI
- Operating range is -40ºC to +85ºC
- 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 analogue output channels with a range of ±10V
- 16 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 greater flexibility
- Open drain outputs are pulled high via a pull-up resistor
