===== ADC FPGA Interface =====

{{ :resources:eval:user-guides:ad-fmcmotcon1-ebz:hardware:ad7401_logo.png?100|}}
The AD7403 Isolated Sigma-Delta Modulators present on the controller board have a 2 wires signal interface with the FPGA:
  * 10 / 20 MHz clock input
  * 1 bit digital data stream output

The reconstruction of the data provided by the AD7403 modulator can be done using a SINC3 filter. A filter model and HDL implementation are provided in the AD7403 datasheet.
Typical filter output characteristics:
  * Output code: 16 bit
  * Sampling rate: 78kHz
The output code resolution and sampling rate can be controlled by changing the filter’s model and decimation. Polyphase interpolation filters are utilized to increase the sampling rate of the system.
