FPGA power-up

Stepping up from the Xilinx Spartan-6 used in XFM, XFM2 is based on the Xilinx Artix-7 35T FPGA chip. With almost four times the capacity of the previous one, this new chip offers plenty of space for a more complex build.

24-bit DAC

Also stepping up from XFM, the simple 16-bit digital-to-analog converters have been upgraded to a 24-bit dedicated chip, with high-end output filters. The analog outputs have then greater dynamic range, higher S/N ratio and lower distortion.

Simplified build

The build is based on two pre-assembled development boards: the Digilent CMOD A7-35T (FPGA, USB, SRAM) and the Adafruit UDA1334A (DAC). This combination allows to get the module running in less than 10 components (about $99 total cost).
