TDA4850

· VGA operation fully implemented including alignment-free vertical and E/W amplitude pre-settings
· 4th VGA mode easy applicable (XGA, Super VGA)
· Multi-frequency operation externally selectable
· 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
· Constant vertical and E/W amplitude in multi-frequency operation
· DC-coupling to vertical power amplifier (TDA486X or TDA8351)
· Internal supply voltage stabilization with excellent ripple rejection to ensure stable geometrical adjustments.

The TDA4850 provides economical solutions in VGA/XGA and multi-frequency monitors. The IC incorporates the complete horizontal and vertical small signal processing.

VGA-dependent mode detection and settings are performed on chip. In conjunction with TDA486X or TDA8351 (vertical output circuits) both ICs offer an extremely advanced system solution.
