Complementary Waveform Generator (CWG) / Complementary Output Generator (COG)

The CWG provides a complementary waveform with rising and falling edge dead band control, enabling high efficiency synchronous switching, with no processor overhead. The CWG also incorporates auto shutdown, auto restart, and can interface directly with other peripherals / external inputs. The COG improves upon the functionality of the CWG with the addition of blanking and phase control.


  • Various input sources inclusive of: Comparators, PWM, CLC, NCO
  • Blanking control for transient filtering (COG only)
  • Phase control for output delay (COG only)
  • Auto shutdown/restart
  • Independent rise and fall
  • Dead band control
  • Polarity control
