Data Signal Modulator

LED Dimming Engine and Protocol Modulation

Features

  • Modulates a carrier signal with digital data to create custom carrier synchronized output waveforms
  • Combine on and/or off-chip source signals
  • Polarity selection on output
  • Paired with the 16-bit PWM to create LED dimming engine
    • Freezes op amp compensation during “OFF”
    • LOAD disconnect for fast output “OFF

Benefits

  • Smooth signal switching
  • Lower code overhead
  • LED Dimming
    • Reduces heat
    • Increases LED life
    • Minimizes color shift
  • Core independent operation
  • Operation while in low power SLEEP
