TBA950-2 Television Signal Processing Circuit
General Description
The T B A 9 5 0 - 2 is a monolithic integrated circuit for
pulse separation and line synchronization in T V receivers
w i t h transistor o u t p u t stages.
The TBA950 comprises the sync separator with noise
suppression, the frame pulse integrator, the phase com-
parator, a switching stage for automatic changeover of
noise immunity, the line oscillator w i t h frequency range
limiter, a phase control circuit and the o u t p u t stage.
It delivers prepared frame sync pulses for triggering the
frame oscillator. The phase comparator may be switched
for video recording operation. Due t o the large scale of
integration, few external components are needed.
