Key Features

  • Fully integrated, few external components.
  • Positive video input signal, capacitively coupled.
  • Operates with non-standard video input signals.
  • Black level clamping.
  • Generation of composite sync slicing level at 50% of peak sync voltage.
  • Vertical sync separator with double slope integrator.
  • Delay time of the vertical output pulse is determined by an external resistor.
  • Vertical sync generation with a slicing level at 40% of pe.
