Multifunction I/O for PMC & XMC FPGAs AXM-A75

The Acromag AXM-A75 is a Multifunction I/O for PMC & XMC FPGAs.

Firstly, there are 16 differential analog input channels. Each input has its own high speed 16-bit A/D converter. Therefore, offering the ability to simultaneously sample all channels. A low pass filter to remove unwanted EMI is conveniently located at the beginning of the analog signal chain. Along with, a programmable gain amplifiers that scales the input and provides a corresponding giga-ohm input impedance.

Secondly, the two quad serial input DAC devices drive eight analog output channels. Each channel has its own high speed 16-bit D/A converter allowing simultaneous updates to all outputs. There are sixteen bi-directional digital I/O channels which provide the ability to monitor and control discrete devices. Each I/O channel is individually configurable as an input or output for greater flexibility to match your requirements.

Features of the Multifunction I/O for PMC & XMC FPGAs AXM-A75 include:

• 16 channels of analog input capable of simultaneous sampling
• 16-bit 250kHz A/D converter on each channel
• Analog input range of ±10.24 volts
• Programmable gain of 1x, 2x, 4x, or 8x
• 8 channels of analog output capable of simultaneous updates
• Each A/D channel includes a 2K sample FIFO
