DESCRIPTION

The TDA2593 is a circuit intended for the horizontal deflectionof color TV sets, suppliedwith transistors or SCR’S.

.LINE OSCILLATOR (two levels switching)

.PHASE COMPARISON BETWEEN SYNCHRO-PULSE AND OSCILLATOR VOLTAGE Ø 1, ENABLED BY AN INTERNAL PULSE, (better parasitic immunity)

.PHASE COMPARISON BETWEEN THE FLY BACK PULSES AND THE OSCILLATOR VOLTAGE Ø 2

.COINCIDENCE DETECTOR PROVIDING A LARGE HOLD-IN-RANGE

.FILTER CHARACTERISTICS AND GATE SWITCHING FOR VIDEO RECORDER APPLICATION

.NOISE GATED SYNCHRO SEPARATOR

.FRAME PULSE SEPARATOR

.BLANKING AND SAND CASTLE OUTPUT PULSES

.HORIZONTAL POWER STAGE PHASE LAG GING CIRCUIT

.SWITCHING OF CONTROL OUTPUT PULSE WIDTH

.SEPARATED SUPPLY VOLTAGE OUTPUT STAGE ALLOWING DIRECT DRIVE OF SCR’S CIRCUIT

.SECURITY CIRCUIT MAKES THE OUTPUT PULSE SUPPRESSED WHEN LOW SUPPLY VOLTAGE
