      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 FPGAs
      • 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

      Mixed Signal FPGAs - Standard Approach

      • 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

      Core Benefits of Mixed Signal FPGAs

      • Reduce your hardware footprint and parts count
      • No active peripheral ICs required
      • Efficient post-processing with low FPGA resource cost.
      • Highly reconfigurable analog-to-digital converter (ADC) / digital-to-analog converter (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


      • 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


      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.
