Description
Vertical part
fV = 60 Hz (M) system
TDA2579C
Vertical synchronization pulse separator without external components and two integration times
Zener diode reference voltage source for the vertical sawtooth generator and vertical comparator
Divider system with t
Features
- Synchronization and horizontal part.
- Horizontal sync separator and noise inverter.
- Horizontal oscillator.
- Horizontal output stage.
- Horizontal phase detector (sync to oscillator).
- Triple current source in the phase detector with automatic selection.
- Normal phase detector time constant is increased to fast during the vertical blanking period (external switching for VTR conditions not necessary).
- Slow phase detector time constant and ga.
