Mixed Signal FPGAs

MLE's patent pending Mixed-Signal FPGA solutions make Delta-Sigma-Modulator technology applicable to your next Embedded System project.

When it comes to processing legacy data protocols FPGA offer very cost efficient alternatives to the – sometimes hard to get – original circuits. MLE's Mixed-Signal FPGA technology further broadens the application space from pure digital protocols to so-called “amplitude-modulated” protocols which require plenty of configurable analog I/Os  embedded inside proven off-the-shelf FPGA devices.


Standard Approach MLE Mixed Signal FPGA
  • Discrete active components required to extend the FPGA with analog I/Os

  • Increased parts count and PCB footprint

  • Additional effort required to ensure simultaneous time-synchronous data processing

  • No active peripheral components, analog I/Os are directly integrated into the FPGA

  • Reduced parts count and PCB footprint

  • Enables simultaneous and time-synchronous sampling, direct and straightforward


  • Flexible data acquisition and monitoring systems
  • Cost-efficient embedded systems with many sensor inputs
  • Voltage-based actuator control, DC motor control
  • Audio Output – that FPGA sounds great!
  • Integrated microcontrollers with reduced risk of parts obsolescence
  • Amplitude-Modulated (AM) protocol processing, for example IRIG


Core Benefits

  • Reduce your hardware footprint and parts count
  • No active peripheral ICs required
  • Efficient post-processing with low FPGA resource cost.
  • Highly reconfigurable ADC/DAC parameter setting
  • Design flexibility: „one more I/O“
  • Greatly reduce costs when applying multitudes of analog I/O channels
  • Reasonable I/O precision, more than sufficient for most of today's analog applications in Embedded Systems
  • ADC sample rate: up to 200 kS/s
  • ADC resolution: up to 11 bits ENOB




MLE provides a suite of Intellectual Property (IP) Cores, reference designs, and design tools within a Mixed-Signal design suite. This complements the "soft" ADCs and DACs with optimized-for digital signal filtering and conditioning which takes the burdon of parametrization away from the user.

MLE provides a three-phase product integration roadmap for new customers:
