The TBA950 compares the sync separator with noise suppression, the frame pulse integrator, the phase comparator, a switching stage for automatic changeover of noise immunity, the line oscillator with frequency range limiter, a phase control circuit, and the output state. It delivers prepared frame sync pulses for triggering the frame oscillator. The phase comparator may be switched for video recording operation. Due to the large scale of integration, few external components are needed.
