Connectors

FPGA-ITX-01 FRONT CAD.PNG

J1, J13 - Stereo Audio Jack

  • 3.5mm stereo connector
  • Jack on card has priority over connection to chassis jack
    • Chassis front panel jack gets disconnected when jack is plugged into the card
  • Stereo pinout
    • Tip: This acts as the left channel signal wire
    • Ring: This acts as the right channel signal wire
    • Sleeve: This acts as the common return wire
  • J13 is header to case jack
  • Minimal LP filter
  • FPGA Sound on our GitHub
  • Using PWM to generate sound
  • How to Generate Sound using PWM
  • Run at frequency well above audio, say 44.1 or 48 KHz
  • Output of filter with 50% duty cycle will produce smoothed average voltage at the mid-point
  • Values > 50% duty cycle will produce a voltage higher than the average
  • Values < 50% duty cycle will produce a voltage lower than the average
