Color Tv Synchronization Deflection Circuit
The LA7811 is an IC containing not only the main functions required for synchronization, deflection of color television sets but also the generator of vertical blanking pulses (open collector output) and burst gate pulses (not sand castle type) and further the AFC time constant selector for VTR With the horizontal jitter at the time of weak electric field strength minimized and the picture distortion due to brightness variation minimized, this IC for synchronization, deflection functions is aimed at reali- zation of multifunction and high quality picture reproduction.
