Abstract From the Canadian patent

A phase-lock-loop circuit of a two-loop deflection arrangement is located in a first integrated circuit. The phase-lock-loop circuit generates a first signal at 32XfH that is capacitively coupled to a tank circuit. A regenerative amplifier stage that is located in a second integrated circuit has an input terminal that is coupled to the tank circuit and an output terminal for producing a second signal. During normal operation the, second signal is synchronized to the first signal. The second signal is utilized in a phase-control-loop circuit of the two-loop deflection arrangement for generating a synchronized deflection current in a deflection winding.
