TDA2579C Datasheet Synchronization Circuit

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TDA2579C Synchronization circuit with synchronized vertical divider system for 60 Hz Preliminary specification File under Integrated Circuits, IC02 January 1994 Philips Semiconductors.

General 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 three differen

Key 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.
