LA7850 - CRT DISPLAY SYNCHRONIZATION DEFLECTION CIRCUIT

LA7850 - CRT DISPLAY SYNCHRONIZATION DEFLECTION CIRCUIT

The LA7850 is a sync-deflection circuit IC dedicated to CRT display use. It can be connected to the LA7832, 7833, 7837, 7838 (for vertical output use) to form a sync-deflection circuit that meets every requirement for CRT display use.

Features
Horizontal oscillation frequency adjustable from 15KHz to 100KHZ.
Horizontal display horizontal (left/right) shift.
Horizontal/vertical sync input operates with any pulse polarity and pulse width.
AFC feedback sawtooth wave can be obtained by applying the flyback pulse to the IC as a trigger pulse.
Horizontal pulse can be set to any duty cycle.
Good vertical linearity due to DC bias at the vertical output stage being sampled and controlled within retrace time.
Supply voltage 9 to 13.5 volts
Supply current total 42 mA
Package DIL-20
