TDA4851 - Horizontal and vertical deflection controller

General Description

TDA4851 DC-coupling to vertical power amplifier

The TDA4851 is a monolithic integrated circuit for economical solutions in VGA/XGA and autosync monitors.

Key Features

  • VGA operation fully implemented including alignment-free vertical and E/W amplitude presettings.
  • 4th VGA mode easy applicable (XGA, Super VGA).
  • Autosync operation externally selectable.
  • Low jitter.
  • All adjustments DC-controllable.
  • Alignment-free oscillators.
  • Sync separators for video or horizontal and vertical TTL sync levels regardless of polarity.
  • Horizontal oscillator with PLL1 for sync and PLL2 for flyback.
  • Con.
