The TBA920s are monolithic integrated circuits designed for TV receiver applications. They accept the composite video signal, separate sync pulses (with the added safeguard of noise gating), and provide a sync output for the vertical integrator. Also incorporated is the horizontal oscillator along with two phase comparators, one to compare flyback pulses to the oscillator and the other for sync phase comparison. The devices will interface with both SCR and transistor deflection systems.
