Integrated Circuit Horizontal and Vertical Deflection Monitor

NTE Electronics 

Application Notes (Cont’d):

Line Output (Pin14)

It is an open collector output which is able to drive a pulse current of 800mA for a rapid discharging

of the darlington base. The output pulse time is 22µs for a 64µs period.

Frame Oscillator

The oscillator thresholds are internally fixed by resistors. The oscillator is synchronized during

the last half free run period. The input current during the charge of the capacitor is less than

100nA.

Frame Output Amplifier

This amplifier is able to directly drive the frame yoke. Its output is short circuit and overload

protected; it contains also thermal protection
