TDA4850 Description
TDA4850 The TDA4850 provides economical solutions in VGA/XGA and multi-frequency monitors. The IC incorporates the plete horizontal and vertical small signal processing. VGA-dependent mode detection and settings are performed on chip.
TDA4850 Key Features
- 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. QUICK RE
