NXP Semiconductors TDA4851
The TDA4851 is a monolithic integrated circuit for economical solutions in VGA/XGA and autosync monitors. The IC incorporates the complete horizontal and vertical small signal processing.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
● Constant vertical and E/W amplitude in autosync operation QUICK REFERENCE DATA SYMBOL VP IP Vi sync positive supply voltage (pin 1) supply current AC-coupled composite video signal with negative-going sync (peak-to-peak value, pin 9) sync slicing level DC-coupled TTL-compatible horizontal sync signal (peak-to-peak value, pin 9) slicing level DC-coupled TTL-compatible vertical sync signal (peak-to-peak value, pin 10) slicing level Io V Io H Tamb vertical differential output current (peak-to-peak value, pins 5 and 6) horizontal sink output current on pin 3 operating ambient temperature range PARAMETER MIN.
